I admit to #4 as well, though I'm not quite OCD about it. If I have nothing better to do while out walking, I'll sometimes try to take an even number of steps (trying to start with the right foot) on a square of sidewalk, or in between cracks, etc. Like someone else said, my stride doesn't match up with this very well, so if it doesn't work out I'll just shrug and try again on the next one.
I don't drive (by choice), so I can't claim #1, but (like a previous commenter) my bike also has an amazing ability to transform into a pedestrian when it's convenient. I also don't have a cell phone, so I can't claim #2, and I haven't done any advanced math since high school, so I had no clue what #3 was.
I do the pocket thing though, and this is pretty OCD, but it's for a very good reason. I have a terrible
memory, so I need to get into a pattern to remember everything. For my work outfit, work keys go in the right front pocket, house keys in the pocket inside
that pocket, wallet in the left leg pocket (cargo pants), and my name badge and pen in my shirt pocket. The left front pocket is left empty for things like kleenex, receipts, or whatever. I hate having things in my back pockets.
I even have a "counting game" to make sure I've remembered everything. I'll touch each part (to make sure it's there) and count the number in my head as I go:
6: name badge & pen
Kind of dorky, but I haven't forgotten anything at home since I started doing it.
I do not do this, but, somewhat similarly, when scrolling down using the mousewheel (navigating by clicks of course) It bugs me when I scroll, and the top of the visible page does not reveal a full line of text. I have to use the 'click-down-themouse-wheel-andgently-oh-so-gently-readjust' thing. Anyone else? Or is it just me?
I don't have a mouse wheel (I use a trackball, not a mouse), but I use a similar function with the "middle" (actually the second left button, mapped as a middle button) mouse button to scroll in web pages, and this allows annoys me. Even if I'm using the arrow keys or the page keys to scroll and this happens I'll whip out the "middle" mouse button (or the scrollbar) to line it up.
I also seem to have this habit of using parenthetical remarks to clarify everything.
