lol, this thread is classic...i gotta admitt i do quite a few of these things.
i always have my cash in order (5-10-20,etc..) and i always take silver coins out of my wallet, leaving only gold. i also have to have all my cards arranged in a particular way.
i have a long goatee, which gets the "wise chinese man" style stroke all the time, i cant help it....even once when i had the goatee shaved off i still went to stroke it and ended up just playing with my chin, lol.
i also have an eyebrow ring which i play with all the time too, i spin the little ball part around and around.
on a random basis ill just crack all my knuckles/fingers on both hands by clenching my fists.....i dont know many people that can do this either.
i always have to have things planned out, like ill lay in bed and think out what i have to do tomorrow and the time scale for it all....eg, i'll be thinking - go to bed at 2am, set alarm for 11am and thats 9hrs sleep, 1hr to wake and have breakfast, shower and get ready for work, 1/2 hr allocated to travel to work, work for 8 1/2hrs...etc...
when im bored ill find some part of my body or a table to play a beat on, like a little drum beat...must be a musician thing. i find my mate who is a drummer (i play bass and guitar, i only muck around on drums) is really bad at this, he's always tapping out beats.
and thats about all i can think of for now...amazing all the little quirks and habits people have.
