As for hobbies, we have something in common in some ways. I like the friends who have the same hobbies with me. Both of us like sports. We often exercises together after school. But he is more outgoing and better at sports than me. Besides, collecting stamps is our same hobby, too. We often exchange our stamps with each other.
About the learning, I think I’m a little smarter than him. Most of my subjects are better than his, so I often help him with his study.
