This one is a doozy!
Define screwed up first of all....
what I consider screwed up is probably quite different to yours!
I mean I would consider screwed up to be stealing a car or killing animals
you may consider screwed up to be playing kiss tag (guilty) or dancing on bars (guilty)
One person I have always had ridiculous nights out with was my mate Ais.
I just stole this off fb. Isn't she gorgeous!
I don't know if I would use screwed up to describe them but we generally had a catch up a few days later and tried to piece our antics together. At one stage, we took salt packets and kept them in our wallets as a reminder to behave. Why they were salt packets I do not know. I assume they were close at hand at the time.
You know, I don't think I really do screwed up things. Crazy things, ridiculous things and at times mortifying things but screwed up? Nah, I'll give this one a miss, blog challenge.
