Batman’s stunt double
This person knows how to look at the glass half full. So his neighbor’s car is blocking his pathway. Instead of crying about it, this person sees this as an opportunity to practice his parkour skills. Who knows, maybe one day he might audition to be Batman’s stunt double. That always seemed like a really cool job.

We’re kidding, of course, as is the guy who wrote this passive-aggressive note. Dealing with a bad parker is one thing, but when that bad parker is your neighbor, it gets more tricky. That’s when the passive-aggressive approach comes in handy. He was able to get his message across while keeping a rather light and amusing tone (except that he’s furious – you can tell by the all caps!).
