What was the most idiottic thing you did?

Mine was when i went to this kids house there parents werent there
and i threw a rock at the kids window.And there parents just came and spanked them.I felt bad for the kid though.

Witch was yours.

I've done alot of idiotic things hard to choose really.
Although a few would be...
Swearing right in front of my mum (It just came out! She pretended not to hear me though )
having a big fight with a friend, she was my best friend when we were younger although we sort of grew apart. We've never spoke to each other since.
And then there's just the general stupidity...

i dont really know probably hitting somebodies car with a baseball bat lol!
