for me it's mainly
- things have to generally be symmetrical or perpendicular to angles and equal distance from edge on 2 or more sides
- volume has to be even
then just little things like
- always finish a job if you start it
- inefficiency at work drives me absolutely bonkers (some complete cretin could spend an entire day manually doing something that could be done in minutes with about 30 mins of original thought or a bit of programming).
- shoes not lined up
- always put things in the same place
Dont think it's really out of the ordinary, just a personality trait, very high attention to detail. My wife on the other hand is a complete scatter brain and jumps into everything two feet first. Good at what she does tho. Neither way is the right way, neither personality is "normal" nobody is normal.
