i'm not the kind of guy who throws a sorry all the time, i do when i made a mistake, there's no mistake in joking with a friend, though he should be sorry for accusing me of something i'm not and getting in a discussion that never concerned him, random accusing people because you see that they use a word you don't like when they are joking with a friend is just bundle of sticksery, but once again it's only my opinion
