最佳答案:

　　Dear Gao yang，

　　Thank you for writing to me.

　　I think it is too early to say whether or not your friendship is over.I don't know what you said to your friend，but it seems you have hurt him a great deal.You need to give him more time to forgive you.

　　It is great that you have tried to say you are sorry.Your friend knows that you want to make up.And if he is a true friend，he will realize that friendship is more important than being angry.Of course，maybe he doesn't want to talk to you again.This means he doesn't value your friendship very highly.If so，have you lost anything worth worrying about？

　　Yours sincerely

　　Simon
