Ever send an email in the heat of the moment and then think about it later and say "OMG! I can't believe I sent that! Gimme it back!!!"

Well, last night I sent a doozey of a letter basically cursing out someone I cannot stand. It wasn't TO the person (I'm not THAT dumb) but to someone else who works with both of us, and is powerless (or unwilling) to do anything to change the situation. This morning I feel down right childish for sending the email and sent another this morning appologizing and telling them to ignore the first email.

Drat, I wish I could just erase it like it was never sent!

I can't be the only one who's done this! Please give me your horror stories to make me feel better about it!
