The gentleman sitting with our patient, holding his hand and comforting him for hours in the middle of the night as he goes through a frightening and disabling illness, is not his "um, friend." He is his husband. Are you twelve years old, or what?
Next time we have a heterosexual couple in I'm going to smirk and blush and giggle and refer to them as "um, friends." Because I know we have policies to be polite about that sort of thing, but that kind of person puts penises in vaginas, and here they are just flaunting that.
