Totally relate to this thread, there's nothing I want more than to not hear people talking. It's the worst thing when you're walking somewhere and there's a couple of obnoxious people talking about inane things or even worse the girls they were with the previous night.

Saw an old lady tell a couple of ~20 y/o guys to shutup in a supermarket doing exactly that. I envy her.

I hear you on that one, the anxiety at least for me is because it's extremely irritating and I feel that I need to say something but I can't confront people.
