I'm going to park close to another car that's on the line.
Why would you want to park too close to another car?
Because they are parked like an idiot.
It's understandable to be upset at a bad driver, but its rude to park too close to another car. You could end up getting your car dinged or create a situation if the other person gets upset.
No, that stupid person deserves it.
I see why you're annoyed with them, but parking too close isn't going to solve anything and it might make things worse. You should just park normally and forget about the situation. Trying to annoy them won't help.
