Why get all bent out of shape? Yes it was rude, but I'm sure she didn't even think about you or the trailer. Most people as selfish and think only of themselves. She was probably thinking is was easy for her to pull in and out. Just put your truck in reverse and move on out.
Warning - long rant in progress
"Didn't think" is the root of the problem. Being self absorbed is the other. People have no clue that the world exists outside of themselves. I could have parked where no one could get anywhere near the shops. I could have taken up many more spots. BUT I was considerate of others and parked well away from the shops and in as few spots as possible. Ms/Mr Dildohead, in their own little world, parked in the most inconvenient place possible. Yes, I could, and did, back up. That is not the point.
We live in a world where everyone only thinks of themselves (or don't think at all). Ever had someone come flying up next to you only to cut you off to get make a turn when there was no traffic behind you? Ever had someone nearly hit you trying to get that one extra car length ahead at a stop light? Ever had someone pull out in front of you because they didn't want to wait 3 extra seconds for you to pass? IT all directly correlates to this idiots parking.
Why is the crime rate up? People only think of themselves not the pain and problems they inflict on others. Why are there so many accidents on the road? People only think of themselves. Why are there so many drunk drivers? People only think of themselves.Why do people text while driving and run others off the road? People only think of themselves. WHy do people ( notice I didn't say parents) abuse, neglect, and abandon their children? People think only of themselves.
It isn't simply that this person parked in front of me and caused a slight inconvenience. I will guarantee you that this person lives their entire life the same way - doing what is most convenient for them and not giving a damn about the consequences.
SO you see, it isn't just one persons parking job that makes me irate, it is the fact that the world is going to hell in a hand basket and people don't even stop to think about it.
My back is all screwed up and my left side is in constant pain because a 96 year old man could not be inconvenienced to wait for someone to drive him where he wanted to go and jumped the median on Freedom Drive in Charlotte and landed on top of my car. Why? He was only thinking of himself, not the danger he posed to the other 8 drivers he hit and totaled their cars, not to mention all the pedestrians that somehow avoided getting hit. To him getting somewhere was worth the thousands of dollars of property damage he caused and the 1 1/2 years of physical therapy it took me to be able to function again.
What should you take away from this long winded rant?
USE YOUR DAMN BRAIN. Think. Not of what is best for you, but stop and think what effect you actions will have on others. It will make the whole world a better place.
I made sure to put a dent no larger than the one they made. That was only fair right?
