There is a wonderful family in our neighborhood with two moms. Now I'm wondering why they don't hide the fact that both of them are women, like the OP thinks they should. One of my project managers is a married gay man, and his husband looks just like a man. I mean you can even tell! They don't even try to hide it either! What is wrong with people?
I'm a 100% hetero woman, and I've been to his house too many times to count. He doesn't hate me, at least not all the time. Sometimes I make him stay late, and at those times I don't think I'm his favorite person.
My husband has been at the women's home a few times, and I've yet to hear them snarl at them. And now that I'm thinking about it I'm rather pissed off! I think I'm a decent looking woman, and neither of them have ever made a pass at me. It's almost as if they think their vows are real.
I'm being horribly sarcastic because your impressions of these people are based solely on their sexual orientation. What kind of history exists between you? How about the guy in accounting who won't give you the time of day? Is he gay? Divorced? Married? Catholic?
You're either giving off vibes or some past action has made them write you off.
