Написать письмо ! and what is your hobby? do you have much free time for it ? do your friends share your hobby or not?

Dear, ...
Thanks for your recent letter. Sorry, I haven't written for so long because I was busy at school.
Well, to tell you the truth, I have a lot of hobbies, for example, chess, tennis, volleyball, football. I have much free time, that's why, i want to play basketball too. By the way, my friends always share my hobbies. I love them.
Anyway, I have to go now to do my homework. Write back soon.
Best wishes,
