I hate rude people.
Sounds like you were looking for things to be 'insulted' over.
Question - what percentage of your interactions over that interval were pleasant?
If you are getting nothing but negative interactions, there may be something about your persona that turns people off.
I am as pleasant a person as I can imagine in random meetings, but I don't always reply to pro-forma greetings from strangers. Usually do, but there are times when the breathing cycle or my personal thought process just makes it inconvenient to utter an immediate response - and then the moment has passed and I let it go. If someone were to make some snide remark because of that, I would think - "sounds just like Rex."
Do you look for opportunities to be miserable?
