I'll tell you what's wrong with smoking pot, cussing, and staying out late:
Like attracts like and feeds more drama and problems into it than a person can handle.
There is the risk of getting caught and having a police record.
Others who do this kind of thing may have dangerous motives in mind when befriending such a person.
It's not safe for anyone. The consequences of doing the above and associating with others who do can be deadly: DUIs, DWIs, fights, disease and such.
With such a reputation as this, it's hard to find any well balanced people who would want to be friends.
I'm sorry about going into such detail, Snowbird, but some others just don't get how dangerous and socially suicidal this behavior is.
The friends one makes while engaging in this wild behavior usually don't have the person's best interest in mind.
Usually, young people don't do pot carefully or use cussing artfully or are careful who they hang out with late at night.
I'd be worrying my fool head off if my daughter was doing this. Already worrying it off with my son. He broke a lady's heart recently and that is horrible.
