"...If you think the people around you are rude, impolite and inconsiderate you might take the time to find out how they perceive your attitude..."

That kinda depends. A couple of years ago we were in Skagway, AK, waiting in line in a shop to buy a couple of tee shirts. The clerk was obviously not having a good day with the couple in line ahead of us. The we got to her, and she became one of the friendliest people in the world. Turns out that the other couple were "jerks". Sometimes you get out of a "relationship" what you put in to it...
