3) "I don't like this" / "I don't wanna" is not really an acceptable reason to be an antisocial ass.

Being in nature, all alone is not social though, is it? Why are people so frustrated? What am I missing?

FWIW, it is dangerous to wear headphones in the city and listen to music, but you can always wear only one side. It is not comfortable, but that is how you remain safe without being an ass.
