Well, although they probably know you have Angie up there, so said it partly for that...a) they may have done it anyway just because I doubt you took his crap laying down, and that's "lesbianish", lol *rolls eyes at society* and b) again, they didn't say it to her or even to both of you, so.
As you know my family is Dutch, so hearing my grandmother refer to the "dykes" amused me for years when I first came out.
