I know this, mainly because I have had after-school duty to keep the car train moving and students crossing in the lanes. Nothing makes you question the lack of humanity when parents jockey for parking when 200+ parents are doing the same. Oh, it gets nasty.
Every negative thing you have heard about parent pick-up is true, and more so.
I know, I know.
Every driver reaches the time of insanity. One time I had the duty of the "hell drivers" in the enter line. Honestly, I had to block the only car lane that cut through and into the student crossing lane. I had to stand knee to bumper to protect a line of children. He revved his motor. I did have an umbrella and began to open it (why? then I thought it was necessary.) He peeled off and drove down the street. 15 min. later he was back, with no luck, and he moved off to the correct lane, after flipping me off.
Oh, people. Sigh.
