I've decided to describe my personality quirks for all the world to see! (All the world comes here, right?) Why? For no good reason. Or maybe to get you to do the same. Obviously these are just the ones I know about and can remember at the moment.
Robot noises. I still make robot noises, and will probably never stop. It's mostly when I'm going up and down stairs. I'll make the little servo noises for leg movement. I also do this sometimes when I'm looking around. Might as well make noises for my head movement, and move my head in a slightly robotic manner while I'm at it. This one occasionally moves beyond sounds as well. At my job we connect to fuel lines in the ground using a coupler (called a mooshead, for some reason). Anyway, there is a handle on top, and when I reach down to disconnect it I will imagine my hand latching on and locking in around it (almost... robotically). There's probably more robot stuff, but that about covers it.
This isn't as interesting (and not as original as my brain likes to think it is), but I like to take short phrases and mix up the first letters of each word. Big Time becomes Tig Bime and stuff like that. I do this on purpose, and the me inside my head thinks this is quite witty. It's not, but you try telling him that. Sometimes it goes further, though. The hotel chain Best Western of course becomes West Bestern, but then I see the word best in there, and west sounds similar to worst, so it then becomes Worst Bestern, and that annoying in my head me finds this to be the height of oxymoronic hilarity. Anyway, that hotel chain is forever renamed for me now.
When it gets really cold at work I'll do anything to not think about it, which usually ends with me singing very bad improv at the top of my lungs (the airport is loud no-one can here me) or doing skits in all my various voices. These get pretty crazy. Then of course there is also practicing accents. It's good fun, but sometimes I sort of get stuck in one, so I come up with accent specific responses in case someone asks me why I'm talking in a crappy Russian accent.
Probably more normal than I think but I like to act out arguments in my head that I want to have, or should have had. Sometimes it gets out of hand though and I actually end up legitimately mad.
And the weirdest is how a generally very private, not socially brave fellow starts this topic in the first place. I swear I had more good ones, but I can't think of them right now. I'll be sure to add more as they come to me. Anyway, tell me your things, too. Tell me!!
