There are no parking spaces in the community, so I have to circle around every day when I come back.

One day I noticed a car occupying two parking spots, so I took a piece of paper and wrote, "Your parking is really good, just like your life, without direction," and tucked it under his windshield wiper.
The next day, he parked correctly.
On the third day, he took up two spots again.
I wrote back, "Did you not understand the note last time? Do you want me to draw parking lines for you?"
He parked correctly again.
