Buhari’s Victory Continues: Woman, With 40 Day Old Baby, Treks To Abuja To Fulfil Vow (Photo)

woman

Since the victory of Gen. Muhammadu Buhari in the March 28 presidential election in Nigeria, many Nigerians have been trekking in solidarity and celebration of his victory from different directions of the country to Abuja, the nation’s federal capital city.

It all started with the 33 year old Suleiman Hasheem, who trekked from Lagos to Abuja in fulfilment of a promise he made about two years ago, that should Gen. Muhammadu Buhari win the 2015 presidential election, he would trek from wherever he was to Abuja, which he did.

The latest in the league of the trekkers is a 35 year old nursing mother, Mrs. Alice Daniel, who is now on her way from Minna to Abuja to fulfill a promise she made also, just before the March 28 presidential and National Assembly elections.

Narrating her story in an exclusive interview with Newsline, Mrs. Alice, a mother of five, said it all started when her husband, Abdulwasiu informed her that he had a dream that President Goodluck Jonathan was going to lose the presidential election to Gen.Buhari.

She said she told her husband that it would not be possible for an incumbent president to lose the election to an opposition candidate, adding that even if he won, he would not be declared winner as was the case in the 2007 and 2011. At the time, she said, she was heavily pregnant and due for the labour ward.

Mrs. Alice said prior to the election, the issue came up again in one of their discussions with her husband and three other people present, where she promised that if Gen. Buhari won the election and was declared winner she would trek from Minna to Abuja to personally congratulate him for the victory.

According to her, she gave birth to her last child on April 2, 2015, and that she was determined to fulfill her promise with the declaration of Gen. Buhari as the winner of the March 28 presidential election.

Mrs. Alice, a Gbagyi by tribe, from Shiroro Local Government Area of Niger State, told Newsline that there were efforts by her husband, mother and some family members as well as friends to stop her, but that her mind was made up to fulfill the promise she had made to herself.

She took off on the foot journey at about 6:00am on Sunday, from Chanchaga bridge, and while sharing the experience of her mission so far, she said it was fun and that some motorists who were ignorant of her mission offered to assist her but she declined, while others gave her money.

When asked of the health hazard of her mission on her and her newly born baby girl, considering the fact that she gave birth just barely 40 days ago, she expressed optimism that nothing would happen to her and her child and that the only thing she looked forward to was for her to accomplish her mission.

Mrs. Alice, who resides at Anguwan Daji, in Chanchaga Local Government Area of Niger State, said if she reached Abuja she will head straight to Gen. Buhari’s campaign office where she hoped to be led to the president-elect.

Mrs. Alice said she intends to walk between 6:00am to 5:00pm daily and rest at intervals.

And as at the time of compiling this report, Mrs. Alice Daniel was already around Baidna Village, near Kwakuti, along Minna-Suleja Road where Newsline had this interview with her, Monday

Sad tale of Peter Obi on how his Parents Killed Thier Children

The immediate past governor of Anambra told a story of his experience with sycophancy in his days in the saddle during an emotional speech at Oronto Douglas memorial Service. According to Mr Obi, He had gone on official visit to a community and the drums were rolled to welcome him. Praise singers were in abundant supply telling him he was the best thing humanity was sighting since the advent of toast bread. They poured all manner of encomia to celebrate him for the wonderful feats he had achieved as Anambra governor.

A normal governor in our degenerate culture would have soaked in all the praise, emit some noises and dole out cash to the band of sycophants. Visit ended and the media takes over the rest and do the needful.

Not Peter Obi. He had the right perception of power as an instrument not to make your head swell but to make strategic interventions in the lives of those you are privileged to lead. His conscience told him those singing his praises could not be a sincere crowd. He took a few steps not too far from the madding crowd and saw three of those guys whom Christ said have the keys to the kingdom.

In seconds they began to rain on their parents parade as the governor asked them to tell him their areas of need. The first one pointed him to the leaking roof in their community school, the second showed him the non-existent toilet and the third spoke about their broken chairs.

“I stood there looking at those kids telling me the truth while their parents were at another corner singing my praises. You sing praises so the local politicians could give you N2000 while you go home to drink dirty water from a well. You defecate in the bush just for a small token.

From that day, I decided that every Senior Prefect in all schools in the state must have my direct line so they could tell me the situation of things.”

The tragedy of it all is that except there is ethical adjustment in our society down the line, those kids would master the way of their parents down the line.

Check out Why Mercy Aigbe First Marriage Failed

Famous Yoruba actress, Mercy Aigbe-Gentry, has revealed why her first marriage did not work in an interview with the Sunday edition of The Punch.
According to her the marriage did not work because she was young, naive and most importantly she had issues with her mother-in-law.

Mercy Aigbe said that her mother-in-law did not want her son to marry from another tribe. “I had a bad experience the first time, so I had some reservations and I just wanted to face my career, even though I loved him. I decided to put my trust in God and just go with the flow. I was happy and scared at the same time.

Then, I was young and naive. Now, I handle issues differently. Also, the major reason my first marriage failed was because my ex-husband’s mum did not want him to marry from another tribe” she said.

Mercy Aigbe went on to clear any notion that has present marriage has been controversial. “I do not think I have had any controversies since I got married. They were just misconceptions. People thought I married a married man and I was a second wife. What they did not know or care to know was that he was already a divorcee when we met” she said.

In April 2013, there were reports that
Mercy Aigbe was allegedly beaten by her husband at an event.
A few days after the couple released a YouTube video dismissing the claims.

Professor asked final year Art student to strip naked

A disgusted mother has spoken out against the requirement by her daughter’s University professor, that final year students go naked in a candlelit classroom, in front of the whole class and professor..

At the University of California, San Diego, this naked final exam is in fact a course requirement for a class in the visual arts department.

They must also perform ‘a gesture that traces, outlines or speaks about your ‘erotic self(s)’, according to the course syllabus.

The angry mother told KGTV, that the requirement is not made clear at the start of the course, and called it a ‘perversion’.
She added that the exam – during which all the students and the male professor strip naked in a candlelit classroom – made her ‘sick to her stomach’.

But professor Ricardo Dominguez insists that he has not had any complaints in the 11 years he has taught the course.

‘It’s the standard canvas for performance art and body art,’It is all very controlled… If they are uncomfortable with this gesture, they should not take the class.’ Dominguez told KGTV.
