I used to drink alcohol at a moderate level, but I've never smoked or used recreational drugs, so I am a very "square" person generally speaking. I dislike it when people smoke simply because the smell of cigarette smoke offends my delicate nose 😅 But I dislike drinking and recreational drug use because I don't like being around people who aren't fully in control of themselves; human beings are bewildering and unpredictable enough even when they're sober, and when they're intoxicated they are even more stressful to be around. I could probably tolerate a boy drinking a very low amount very occasionally, but I think that would be my absolute limit. (I should really date a Mormon boy!)
