Obsessive-compulsive walking patterns / cracks / lines / etc.

[mmbt0ne]

No cracks.

If I do step on a crack, I step on the next crack with the same part of my other foot, even if it means completely altering my step pattern. As I'm stepping over cracks, I have to step over an equal number of cracks with each foot, so I try to make a pattern for my steps. On the walkway in the middle of campus I go 5-steps 3-steps on each section (they're not the same length).

Equal colors.

If there is tile, I either stay on one color the entire time, or have to have equal steps for my two feet on whatever other color I come across. If it's a white hallway with something like this:

w-w-w-w-w-w-w-w-w-w
w-w-w-w-K-B-w-w-w-w
w-w-w-w-B-K-w-w-w-w
w-w-w-w-w-w-w-w-w-w

I have to either step over the entire length of the decorative tiles (equal times of course) or if I step in the path of one of the colors (a white tile that is on the same y-coordinate as a black or blue tile) then I have to step on the same position tile at a later point down the hall.

It's a lot of different manifestations of those 2 things, but that pretty much covers it. I'm a lot better when I'm talking with multiple people though, so long as I can make it the whole way without noticing. If I notice halfway through then I start thinking about it and wondering what I've done so far so that I can balance it out.
