LOL. OK, one of my DU secrets is that if I KNOW I'm going to get shit for a post and I see that...
...someone's responded to a post of mine, even before I click on the "My Posts" to find out where the response is, my left hand is already flipping the bird at the monitor as my right hand moves the mouse to click on the response. Most of the time I don't even raise my left hand, it's almost entirely a subconscious response. I'm pretty sure I've been doing this (mostly) without thinking about it for at least five years, now.
I started to wonder recently if I've ever done this IRL without knowing it.
ps - A friend was watching me use DU and she got to sniggering. When I finally asked her what it was about (I didn't realize she was watching me), she did an impression of me moving the mouse around with one hand while the other, at my side or in my lap, was reflexively flipping the bird on and off, like flashing spots on an angry cuttlefish.
