my pet peeve is when someone asks you to stay out of there life (ie: don't call me, don't e-mail me, don't show up any place I may be, etc...) and you respect their wishes, but then they call you several times (but don't say anything {helloo... caller ID}), e-mail you a couple of times (one of which is for some perceived wrong which is sooooo far off base it's not even funny) and when you respond to them, they just ignore you... well... that just irks me!!!
OK, I've vented and now I'm done.
