Good gracious, I laughed so many times at Sakuracon I don't even know where to begin...
All right- there was some annoying guy flirting with my friend- she's a lesbian, definitely not interested. She flips him off, he leans over and goes, "Sometimes that can be taken as an offer." She tells me this, and after a while I take him into the hall and say, "What's your deal with (name)?" And he says, "I just wanna make her happy." I answer with, "She has other people to make her happy- mainly me. I know you mean well, but back off, okay?" Didn't mess with her again. I told her later and we had a good laugh about it.
My friend's friend was looking for this one girl for a long time, and then my friend goes, "Hey, he's dancing with her." I look over and reply, "Umm, that's my friend (name)." We kept squealing about it later on. Doncha love the irony?
I'll try to remember funnier things that other people said, not just myself. When I do, I'll be back.
