One possible version:
My good friend is Bill. We met on the first day of school because we were in the same class and he sat next to me. We both liked playing football, so we became friends quickly. At that time, he was shorter and heavier than me. But now, he is as tall as me.
Bill studies harder than me, and he does well in all the subjects. He always helps me with my schoolwork. He is more outgoing and funnier. He often makes me laugh. I like to be with him a lot.
A friend is easier lost than found. I feel happy to have such a good friend. I hope our friendship can last forever and both of us can be better.
