I think you are right that it’s that particular scene that causes these problems as it’s not common to run into that many poorly behaved unstable people in other places. Likely abuse of various substances contributes to these outrageous behaviors. I go to all kind of places and the only time I ever run into horrible behaviors is when alcohol/pot/drugs are involved and on occasion it could happen in the most upscale venues in the middle of the day if people partake in substances-witnessed that!

Having said that I don’t think you must quit music. There are music scenes that are way more appropriate. You recently went to a brewery with music scene and seem to enjoy it? Were they better behaved?

Of course there are jerks in every walk of life. The way to avoid them is to take it slow getting to know them. I bet if you took time to get to know that awful woman, you’d never go on trips with her. If you take your time getting to know people before you go places with them or invite them over etc you’ll avoid many issues. It might appear that people all suck but of course only some do, but you can avoid them

I say two good friends is a good start and honestly two decent people is better than 20 terrible ones!
