>Wondering how people have the audacity to try to talk to you in public when you _clearly have your headphones on!_ (just one of the things I've heard here) is not okay. Not for society, and not for you as an individual.

So you're saying it's okay for people to walk in when you're going to the bathroom and bother you? Or that it's okay for people to wake you up when they want to talk to you?
