OCD (Obsessive/Compulsive Disorder)? Do you happen to also be immeasurably wealthy, like Jack Nicholson’s character in “As good as it gets?” 'Cause that would be cool.
I avoid cracks/lines/joints in walkways.
If tiles are large and pronounced enough I try to avoid stepping on the lines.
I might avoid some of the other lines you mention (like shadows) but not imaginary ones - that’s just weird
I blame it on an incident when I was young, chanting “step on a crack, break your mothers back” and when I got home Mom had something wrong with her back. Even at the time, I knew that there wasn’t a causal relationship, but I still avoid the things.
May not be related to that at all, since I count stairs and do some other minor (very minor) OCD-type things. I don’t think I’m OCD, but I can understand a lot of their quarks… NO, sorry - “quirks”, not quarks.
I only partially understand quarks, and I thought there used to be a 2-spin, but I can’t find a reference anymore. Seems like everyone is all “quarks are fermons and thus 1/2 spin particles” with their snooty voices and their fancy MP3 players.
Damn kids.
I also have a hard time letting an argument drop, even after I discover that I’m wrong (which rarely happens). I’ll keep researching and documenting that the losing side was indeed incorrect. Lucky I’m not afraid to lose an argument, providing I learn something in the process.
And it seems I hijack threads… Sorry Mellivora capensis
I have it only if I think about it.
I then usually draw imaginary lines from all 90 degree corners and try not to step on these.
Sometimes I even count all these imaginary lines I go across and I try to come to an even number.
It was a lot worse when I was younger, I now do it more to amuse myself.
