Poke a hornets’ nest, get stung.
Another class of idiots-the ones who park so close to your driver’s door that you can’t get into your car.
When they do that, there are invariably many, many open parking spaces in the immediate area, but the one right next to your car is the only one they will consider using.
The last time it happened to me, it was a Cadillac, so that explains everything.
