When eating Lucky Charms, I'm never satisfied with the oats to marshmallow content ration, so I'll spend a few minutes throwing out some oats from the bowl. Pour in another batch and repeat until said ratio is acceptable.
When in the shower, I put on performances in my head and gestures of albums or songs. Most recently, I've completed a whole set to The Weeknd's mixtape House of Ballons. I go in with the detail. Backup singers to the slight right. My girl dancing provocatively (some songs) with me sitting in chair. Facial expressions at key lines, etc. If I could sing (secretly wish I could), I'd probably only be able to perform in small venues where subtlety can be noticed, or else my live performances would be the death of my career.
I have to use my own utensils, even while at home. I have a pair of plates, a bowl, a couple forks, spoons, knives etc that are clearly mine. Every time my cousin comes over this jerk wants to use my stuff. I cringe, then have to wash it myself a second time after someone already has.
Speaking of the shower, I hate the feeling of the tile on my feet. I stand in a basin. Or if away, I wear flip flops, for both hygiene and avoiding that cold, unnatural feeling.
There are a few things others have mentioned that I do. The facebook thing about checking it a day later or so, definitely.
