Are there any occupations you uniquely oppose the existence of?
I did retirement home training and used to think it was a sweet job. Then I got in the business and underestimated how demoralizing it was as they give you the easy elders in training while the others make you, or at least me, really think of the fact the job just amounts to an unkarmic freebie.
Guidance counselors. One of them tried to convince my parents that I was on drugs...in 4th grade. Turned out that I had an undiagnosed mental disorder.
I had similar experiences. It's like there's a small but noticeable subset of the population that wants to pin "drug user" on any person they meet and think is weird. Meanwhile, actual drug users are everywhere and mostly manage to act normal.
