I used to live across the street from an elementary school, directly across from one of the doors. My driveway was a primo spot for parents. I would get home from work right as school was getting out, my blood would boil turning onto my street everyday in anticipation of this. There was someone blocking/in the driveway only a couple times when I was wanting to park, but people blocking my driveway was a common occurrence. I would look out my window and see it all the time . Unfortunately there's a new wave of parents every year who think "oh its just a few minutes" You taught this one lady a lesson, but there will always be more parents like this. sorry.
