Re: Friend being angry
You've made phone calls and sent emails.....you can attempt apologizing face to face.
If you have apologized sincerely.......then you have done your part. So now all you can do is leave him alone.......give him some time and space to calm down.........and if he values the friendship enough......he'll get back in touch with you. He knows how to contact you if he chooses to do so..........so leave him alone. Don't bug him anymore.
