Things about people only bother me because I allow them to bother me. If I look in the mirror I am looking at a sometimes annoying guy. I think the main problem comes from having an expectation that is too generous. Expectation- People will not almost run over you in the grocery store,everyone there will be patient. People will not reach right in front of your face to get something.People will say "excuse me". Well I hate to be the bearer of bad news.....lol.
Expectation- People will pick up after themselves. I don't know what house your living in but it ain't mine.
Expectation- People driving will wait their turn at a 4 way stop. People will not ride your rear end like they are about to run out of street.When you honk at someone who almost hits you out of inconsideration, that person will not throw you the middle finger, but realize their error.
Expectation- People living in close proximity to other people will notice and respect their neighbors space. Reality- People seem to like making it known that they are on the planet in the loudest most irritating ways they can come up with.
I guess the answer here is to expect very very little from people and then if someone is actually considerate we are pleasantly surprised.
