I dread encounters with folk like you when I leave the house.
I get that some humans are naturally more socially inclined, so you require constant affirmations and acknowledgment from everyone around you or you stop feeling good about yourselves and whatever, but this kind of self centred attention seeking that has you going out in public and deciding everyone should want to talk to you if you just go up to them and start talking- is incredibly fucking selfish.
Why do you think you're so special and important that you get to interrupt people going about their lives and make them listen to you talk? Nobody owes you this. If you want to talk at people start a fucking podcast and let me buy my apples in peace.
Objectively: It's entropy, life is part of the process for dismantling the universe.
Subjectively: It's whatever you like. Personally I find a lot of comfort in the objective view.
