I don’t have this problem because whenever I’m in public I have my headphones on. Even if I’m not listening to anything on them they’re still good enough to muffle every other sound blasted by others.
It’s easier to adapt myself than it is to educate everyone else I guess.
I don’t disagree with the last part.
The thing is that either I shield myself whenever it’s possible so I don’t get annoyed over other people’s actions and get to live a reasonable nice day, or I let myself be annoyed by them and don’t enjoy my hiking or sitting in the park experience anyway.
Either way I don’t really encounter these people unless I’m using public transportation. If I’m on the beach then I sometimes encounter them but then it’s chill and I can just find another place.
