I returned to Abuja, the capital of Nigeria ,after college graduation. I had been there before my mother became a minister.

Two weeks later, I told my mother I was bored.She said, “Here’re the car keys.Go and buy some fruit.”  36  ,I jumped into the car and speeded off.

Seeing me or rather my  37  ,a boy sprang up(跳起来).  38   to sell his bananas and peanuts. “Banana 300 naira.Peanut 200 naira! ”

Looking at his black-striped bananas,I  39   to 200 total for the fruit and nuts.He  40   .I handed him a 500 naira note.He didn’t have  41  .So I told him not to worry.He was  42  and smiled a row of petfect teeth.

When, two weeks later, I  43  this same boy, I was more aware of my position in Nigerian soeicty.I should  44   this country as the son of a  45  .But it was hard to find pleasure in a place where it was so  46  to see a little boy who should have been in school selling fruit.

“What’s up?”I asked. He answered in  47  English, “I…I no get money to buy book. ”I took out two 500 naira notes.He looked around  48   before sticking his hand into the car   49 the bills.One thousand naira means a lot to a family that  50  only 50,000 each year.

51   it’s right,but this happens everywhere in the world.I wondered if my little friend had actually used the money for  52   .

After six months’work in northern Nigeria,I returned and saw him again standing on the road.

Are you in school now?”

He nodded.

A silence fell as we looked at each other, then I  53   what he wanted. I held out a 500 naira note. “ Take this.”

He shook his head fiercely and stepped back  54   hurt.

“It’s a gift. ”I said.

Shaking his head again,he handed me a basket of bananas and peanuts, “I’ve been waiting to  55  these to you.”
