Sigh. Some people.
Ran into another traffic SS on the way back from dinner. We were turning out of the parking lot when SUV SS came roaring out of the gas station across the street, forcing Dad to slam on the brakes and still coming within mere inches of taking off our front end. Now, to be fair to SUV SS, she did have the right-of-way in this case and Dad felt very sheepish for inadvertently pulling out a little too far. That's not the SS part.
The SS part is that she locked eyes with Dad, screaming and hollering and flailing her arms and flipping him the bird because he was preventing her from cutting diagonally across four lanes of traffic to get into the right turn lane. And kept screaming, hollering, flailing and middle-fingering until she actually turned and couldn't see us anymore without causing a very severe accident.
What makes people do things like that? *sigh*
