I can no longer express myself. Language defies  exactly what I want to convey. It's not that I am limited, it is as though expression or the ability to express  one's self has some kind of undefined boundary.  It's like the blinkers and lights on a motor vehicle, all intentions of movement are clearly marked and easily comprehended by different colored lights and blinking signals, but stray from the norm of  simple 24/7 movement and all comprehension fails. I drive a large service vehicle and I usually have to park by backing in. This of course, takes a few seconds longer and requires a larger area to complete, but few people in their BMW's or Honda Civics can even contemplate this eventuality. 
Backing in was and still is the best mode of parking due to the fact, that when you leave, you have a full view of what is in front of you unobstructed. I suppose with cars that have tight turning radius's and back up cameras this is no longer a concern and the brains of those who operate those vehicles are no longer able to engage the fact that there are different types of vehicles on the road with different demands. 
One such specimen I engaged this evening sitting in her BMW started to throw garbage out of her window. She appeared to be a well human being with no obvious degenerative problems, but she still threw garbage out of her window for no other reason than convenience. I rolled down my window and notified her that she had dropped papers out of her window. To this she responded by spitting on the tarmac. A young lady, no more than thirty, pretty, in a 40k something car and lacking any form of social class.  This sort of behavior, at least when I was growing up and I'm no angel, was frowned upon. 
There was a sense of shame when people did things that polluted or infringed on others in the past, but now, no one gives a shit.
