wait til you figure out that all of human history is one giant cycle of people being incredibly cruel to other people for incredibly tenuous reasons and realize this cycle will, presumably, never end; and thus every interaction you have with other people is if not driven by transaction (what can you do for them), likely to be driven by cruelty.
sweet dreams, it doesn't get better.
if the vast majority of your interactions with other people are neutral or positive, absent of transaction or cruelty, I'm very happy for you. genuinely. Unfortunately your personal experience, however, doesn't invalidate mine; nor does it invalidate the mountains of human awfulness throughout history and up into the present day that I could list off to prove my point -- keyword being 'could', here, as I'm not very interested in arguing, or in pissing on the parade you're apparently having. If nobody's pissed on yours, yet, why would I want to be the one to do so? so go, be happy, dismiss what I say as "cynical doomer shit" while you still have that fleeting luxury.
