Once, my schedule of classes dictacted that I had to leave @ 8:00 a.m. in order to make my first class twice a week. After a couple weeks of taking the same route which included a two-lane highway for about 15 miles, I kept coming upon a red Ford sedan that became the bane of my existence for the whole semester. She must have been going to work, classes, or something scheduled too because her entrance was made like clockwork. The problem was that she drove at least, if not more than, 5 mph UNDER the speed limit
... ALWAYS ... and she wasn't even OLD.
I couldn't really pass her because the oncoming traffic was too heavy and any alternate route took me @ 8 miles out of my way. I ended up having to leave 10-15 minutes earlier just to ensure that the dipshit was seen in my rearview mirror.
