Here is a question for today if fact I would stretch this further and say are most people in real life even worth paying attention to ? Because to me it seems like humans Excel at being around eachother but yet ignoring eachother why don't humans just kill and attack strangers like animals ?
No, many people will hurt you "without" realizing it. Less will hurt you realizing it. Besides this, most people are wrong about "easy" conceptions.
Now where it is yes: to interact positively, even, in fact especially, with strangers by way of mouth, gifts and every other way is something you as a human being, as a social organism (this includes primates, wolves, bacteria) thrive on. To limit yourself to friendliness only with those whose opinions matter is going to net you a bad life, regardless of even the riches you have. That probably plays into why inteligent people are lonely. Naturally less friends, idiots are a headache and a heartache.
