This pertains more to sexuality than gender. Here goes:
Me: I am attracted to women and have zero interest in being with a man.
Good Christian Friend: That's ok. Everyone's bi these days.
Me: I am not bi.
GCF: Well, I didn't say you were bi.
Me: Uh...
GCF: You could always meet a Mr. Right, fall in love and end up married someday. It happens. God works in mysterious ways.
Me: Just so we're clear....I don't like men.
GCF: Ok, well, God could have a different plan.
Me: Well, if God's plan for me involves a man....whatever, screw it, I can't continue this conversation.
GCF: I promised God I wouldn't date until God showed me the One....and he did, when I was 19 and it was awesome. Don't you want your life to fall into place like that someday?
Me: So, how is your cat doing? Is he still sick?
