Smoking medically proven to cause rudeness...
It almost seems as if smokers have decided that since they are not worthy of self-respect, that they are not required to extend any measure of respect to those around them. What really astounds me is the apparent disdain that smokers have for non-smokers. "I'm through with this cigarette, therefore I shall litter the ground with the smoldering remains of my self-imposed destruction." Why can't they put the butt in the ASHTRAY that has been so conveniently included in their automobile? Do they toss butts out of their windows in front of their own homes? I highly doubt it.
Now that I think about it, I guess it's not really that big of a deal. I can always just start tossing my Wendy's wrappers in their front yards when I'm through with them.
After all, it is my RIGHT to enjoy that juicy, artery-clogging goodness when I am driving around.
Who is it going to hurt?
