or pick up your dog’s shit, then that’s selfish
If you didn't notice that you have only one waste bag, and your dog had a need in more than one place, and you'll be late for something, and in addition to that generally have a bad sense of time and place (ASD definitely, BAD or ADHD probably), then it's not.
It’s not anywhere near the same category as being too burnt out to do the dishes after a double shift
Imagine that sometimes people wake up this tired. Someone left an electric light on outside and you can't force yourself to cover the window - bad sleep. Forgot to drink some water before falling asleep - bad sleep. Ate something salty in addition to that - horrible sleep.
If you have roommates and you left dishes in the sink, you are being selfish.
Suppose so.
If your kids have an early baseball game, and you are too hungover to show up, then you’re being selfish.
Hangover is a bad feeling.
Not returning a cart should be punished with crucifixion though.
