I did a similar thing with a window not that long ago I was waiting for my mate to come down from his flat and my handlebar was leaning against the glass of the front door it went through and smashed, that window had been replaced three times in the last week. One of his neighbors came about 30 seconds later and opened the door then realised the glass he was furious I said I didn't even realise it was broken. Soon after my mate came down and about 5 other neighbors they were all really pissed off we then rode off and they never found out it was me.
Another one was last summer my ex-girlfriend dumped me on the first day of our holiday (7 days long what a bitch!) and admitted that she had kissed another boy when she was at a camp in america a week before. I made her feel really bad about cheating on me but I had slept with three different girls while she was away and kissed a few more. I found her diary by mistake and read it and it said that she had shagged this south african surfer (Dickhead) and not just kissed him so she lied to me! the next day I went out a bought a diary with a padlock on it wrapped it up and gave it to her on the last day of our holiday Her face went from being extremly exited to really guilty she looked petrafied and was saying sorry all the time we were on the plane I made her feel really really bad although I had slept with Three other girls.
Oh well I supose theres a time in life for cheating.
