I feel like people care to much about insignificant things like gender, race, history, social status, location of birth, date of birth, ect. It just seems exhausting to always be forming opinions about people. I mean, if you are a store owner, do you care who buys your products?
It just seems so.. trivial.
People also care about ‘idols’. I don’t rationally get it. Even if they have a better abilities in a game, that doesn’t mean that you should have a reason to pay more attention to them. Honestly, if anyone was to be my idol, Tanaka from Tanaka-kun Is Always Listless might get that position.
You have familial relationships/histories with the people you know. This separates friends/associates from strangers. This helps to, over time, develop your culture as similar to theirs.
