well, if you think you are wrong in the 1st place,
then i suppose you shld apologise.
don't just say sorrry, perhaps, let him knw that you wan to provide
him an explaination, if he ignores you, give him some time, leave
him alone 1st, but not without e-mailing him to give him a full
explaination,
then let him knw that you are going to give him some space of his
own when he has cooled down, he can come find you again.
its probably that he just impluse that caused him to be angry with
you bahx.
if your explaination is not accepted, then i guess, you just have
to come up with other form of communication bahx.
man has invented the knowledge of speech and writing for
communication, do not waste such basic knowledge and lose someone
you truely treasure.
