For some reason, when I woke up, I had a flashback from a past:
Me as a kid, playing with calculator and laughing (For some reason, when I was small, I found calculators very fun and liked to play with them). And then trying to show fun things, which I discovered, playing with it, to other kids. But other kids didn't understand, what was so fun in digits, which were dancing on simple shabby calculator's display. When they saw how I'm laughing on it and how it makes me happy, they seemingly felt disgust toward me (They probably thought that I'm fucked in the head - as I can understand now).
It wasn't direct violation of any taboo. It didn't carry any aggression or provocation in essence. And yet, it was enough for distaste to appear (!).
And after remembering it I thought. The boundaries, in which society tries to put us, are so narrow. It's so easy to earn sincere disgust of some part of people, just by making a little step aside from "norms", by doing something they don't understand. When I tell about it, many people don't understand what I mean, because they take these norms as something which goes without saying.
No wonder, now I keep aside from people, who has too narrow understanding of "normality", whenever I can. Now they look repulsive for me not less, than I look repulsive to them.
