When I was young, l used to play football. (American football or soccer? In English, people will understand you differently depending on where the listener is from unless you specify which you mean.) It was my favorite sport. And I always played it with my cousins and my friends. I played it in the street. But now I'm not used to playing it. I love another sport. My new sport is tennis. I played it at my university with my college friends. It is very interesting.
