This reminded me of myself age 8-9 when I would get stressed if I didn't "undo" any rotations of my body, or rounds around a table. Quite to the annoyance of my teachers and parents. Did anyone else have a phase similar to this?
If I'm walking on a sidewalk and one foot falls on a crack, I have to step in a crack with the other foot, and the crack has to land at the same place on that foot. If it doesn't, it creates additional imbalance that must be fixed by stepping on a different crack with the first foot in the position the other crack connected on the other foot. This is very silly, but it must be done. It also disproves the hypothesis that stepping on cracks breaks mothers' backs because my mother has never broken her back and I've been doing this since childhood. I'm 39 years old. That's a lot of cracks.
I just realized the theorem could be reworded slightly: Step on a crack, break a (not your) mother's back. What if I've been inadvertently cracking spines on the other side of the planet this whole time?
I also do this all the time. It has to be even or I get very annoyed. I also have to step as hard or as soft as the first one or it creates another step I have to do
And if you take a short step on one foot to hit the crack, you now need to do a normal step on that foot onto a crack and a short step onto a crack on the other foot
