Character's boss is dining at the home of Character and his partner. I need offensive remarks Boss can make. Now, I can come up with or Google homophobic remarks on my own, but Boss isn't a homophobe. Far from it. He bears no animosity towards gays in general or Character and/or his partner in particular, but he (Boss) is a blowhard who has no social skills and doesn't think before he speaks.
So, what can he say?
If it helps, same-sex marriage is probably recognized in the jurisdiction where Character lives; I've not yet decided if they've availed themselves of this.
