I end up deleting someone from my LinkedIn connection list about once a month, and always for the same reason: they've made it clear that they don't do a good job navigating business/social interactions.
I accidentally deleted over 13,000 messages from my email account and didn't flinch. Well, almost. There was a feeling of panic, but it was followed by a Zen-like calm. Had I effectively erased the past?
Dear Hackers: What did you get from assaulting my e-mail account? Nothing. No one fell for your foolish ploy. What did I get? I got an amusing day catching up with friends and the therapeutic opportunity to clean up my contacts.
