Right now I am miffed at my various friends who insist on messaging me on MSN even though I am blatantly in AFK status, and then getting all hissy about it at a later date. I even kindly put an auto-AFK facility on incase I go away from the computer for long periods (which I often do) so people know I won't reply. Stupid MSNians.
Have you experienced this phenomena recently? Does it grate on you?
