I loved the high school there, and then I got a degree in engineering at college and worked in fashion. I had a great life, but I realized I had forgotten where I had come from. In 2004 I started the MacDella Cooper Foundation (基金会). We sent clothes and school materials to more than 500 children at five orphanages (孤儿院) in Liberia! I also ran a scholarship programme.

It was not just that you were really fat and shouted so loudly. Everything about you was scary. All the teachers were afraid of you too. But you were very kind. You would shout at us if we'd done something wrong in someone else's lesson, and then you would go to apologize to that teacher for what we had done. Do you remember how you made me draw and paint that photograph of the tennis player Nastase? It was too bad at first but in the end I was so proud of it. You could even see the veins (血管) in his legs. \— and you were right. There was a time when I did really well in everything but Geography, and you said, \done quite well this year, but I was only let down by his Geography where he didn't work hard enough.\You rewrote it, saying, ”Simon has done quite well except for Geography, which he's not very good at. \
