Undies

I don't really know how it happened but I unintentionally stole a girls underwear last night. I went to some kind of impromptu party after boxing day drinks and was quite intoxicated, having a bit of a dance etc. and I think someone threw them onto my shoulder, then I may have pocketed them. Have no idea why. I guess it probably seemed funny to me at the time, but this morning when I woke up on the floor of my friends house and remembered that I'd taken them from the party I was completely mortified. I'm trying to get Petra to take the blame and give them back, but she's not into it and reckons she's gonna chuck them. I'm so embarrassed. Don't know what I'm gonna do next time I see her.
