Serious answer? Because if everybody in the world was an arse, the world would be a seriously shit place, and if you’re a well adjusted person with a decent level of empathy, being a decent human being makes you feel better even if all around are being selfish. I can’t speak for everybody, but I certainly get a certain amount of satisfaction out of being nice to other people even when there is no direct reward.
As for other people’s behaviour, then if there isn’t anything you can do to change it then I’ve found the best thing to do is simply ignore such people as irrelevant (it’s only when somebody I otherwise respect does one of those things it causes me issues).
Well thank you for taking the time to write a serios reply Aracer. I’m still seething about the shit in bags but the rest of it is obviously just daily nonsense. The problem there though is judging how and when to interfere, without becoming an archetypal busy body.
Take the women at the school. Speed up to the gates, and park across them while everyone else makes an effort to park along the road. Then they speed off. I feel as though a jovial person could tell them in a light hearted way to have some consideration for school buses, other people’s children and well, disabled people, but if I tried to it would probably come out like a murderous threat.
The obvious answer is to email the school or talk to the principle, which seems petty and underhand.
