Not quite misheard... but overheard in the bathroom:
We were at a jazz club and the band was taking a break. I'd just started washing my hands when the bathroom door was slammed open and a woman on her phone came in. This is the side of the conversation I overheard while sloooooooooowly washing my hands.
"No, I'm not home, I'm out."
"What do you mean, 'where'? OUT, I'm out at a club!"
"With my girlfriends, that's who. Sara, Jenny, and Megan."
"Yes, of course there are men here in the club. It's not an all-girls club."
"No, I will not walk out and go home right now, we're having fun!"
"Well, if you don't trust me enough to go out with my girl friends, then maybe we shouldn't be getting married tomorrow!"
