My mum's boss is gay, and his boyfriend is the nicest guy i have ever met, he's really generous to everyone at work, like always going in giving cakes, sandwiches, chocolate and a good laugh to everyone there.
He's cool, and i have no problem with anybody, that doesn't have a problem with me (i'm not gay by the way)
I also used to say "ahh that's gay!" when something didn't go how i wanted it to, but i grew out of it
