OK, I'll kick this off
1) Went on a date with a girl to the flicks, got up halfway through, pretending I was going to the toilet, then walked out, ran round the corner and got a bus home alone
2) Gobbed in a McDonalds employee's face
3) Hit my dad across the face with a hoover (to be fair, he did have a kitchen knife in his hand at the time)
4) Didn't ring my ex-girlfriend back the week her dad died (deliberately) ; also said something extremely nasty to her which I've always regretted since, even now we're not in contact
5) Had a brief fling with a married woman with a kid, got bored, disappeared and ignored her calls, even though I'd clearly hurt her
6) Threw a firework at a parked car
None of these incidents, except 3, were provoked or out of revenge, and therefore I have nothing but regret, and if I could somehow go back and change things, I would
Und du?
