Common Courtesy Or Common Sense?

Redbush is heading into town again today to do some errands and to bear the traffic and the people.  Do you ever wonder what comes into people's heads sometimes, or are they just too busy to give a sh-t?  There's the driver who doesn't have more than a pinhole to get between you and the person in front of you, but, somehow manages to  sandwich- squeeze his vehicle into the spot while you slam on your brakes.  There's the person in the supermarket who races to get ahead of you in the line like it's the last place on earth, or, like he is going to gain at least 10 minutes in his heavy schedule.  Or, the person who can see that you are looking at an item, the last one on the shelf, and takes it right from under your grab.  Then we have the long lineups at a supermarket, and you're almost to the teller, and, notice that the person in front of you has one item (that's why you chose that line), but, as this person goes to put the item on the grocery belt, she waves in her friend who has two carts plumb full to push come into lineup without so much as looking at you, or " oh, I'm sorry, that was rude, I guess I should go to the end of the line. "  Then you get up at some ungodly hour to go in to get your blood test to be the first one there because you know the lineups can be long if you don't get there early.  You offer this person who gets there three-quarters of an hour after you do your seat , but they refuse only to butt in front of you when the door unlocks so that they can be  the first one at the counter.   Yesterday, Redbush waited with her pickup backed up ready to back into a spot because she could see the person was leaving and because it was a nicer wider spot for her pickup.   Redbush most often backs into spots because she finds it easier to see the parking lot this way and to see people backing out of theirs.  She was about to back in to the parking spot when a large expensive looking car whipped into the spot. Redbush slammed on her brakes  once again.  Getting out, this well-dressed older-looking b-tch looks at her, shuts the door and makes her way into the store.  Redbush had to bite her lip once again.  She looked at the man who backed out because he was still sitting there in shock shaking his head.  Does this ever happen to you?  What would you have done?  Do you have similar incidents?  Is it just common courtesy, or common sense?   Redbush is wishing you a great weekend with lots of sunshine, nice weather, and lots of  kind courteous people in your life.
