Does everyone go around secretly and silently (or not so silently) hating on the people around them all the time? Did I miss the memo?
No. People don't bother me so much -- and certainly not kids. With the exception of the pervs who harass me on the streets day to day (along with every other young woman), I don't get annoyed or angry with people often, and I'm glad I don't have to go around in the constant state of irritation that people like the OP are cursed with.
Sure, every once in a while a very rude person will bother me -- or if I've had a particularly bad day, but overall, why worry about them?
I do think I have a lot more patience than most, though. I must, teaching kindergarten.
