There's this amazingly weird and sad story about a woman who died while trying to enter her on-again-off-again boyfriend's house through the chimney. Yes, it's about 10 times more insane than anything most of us have ever tried, but poor judgment plagues the brokenhearted.
I've sent a regrettable number of emails, and I have a friend who secretly blogged about her after-relationship only to have it haunt her. As long as we don't delude ourselves into thinking we're Santa, we're probably safe, if not entirely sane, and we'll probably learn something from the whole ordeal. What questionable postbreakup behavior do you regret?
