Last year, my Boyfriend and I stopped by one of my friends houses, and they met him for the first time in July and then the second time in December. Both times my friends kept calling him Michael instead of his real name Brian. So my Boyfriend didn't like this and felt that me and my friends were being rude, and they should have known who he was. To me, it didn't bother me at all, they just mistaken his name no big deal but it was a big deal to him. So I am left with asking, what should I do, if other friends of mine, that I introduce my Boyfriend too, make this mistake and this whole thing happens again? What would you do?
