You Brought This On Yourself
I know it’s normal in some places, but personally, I find it really irritating when people try to claim that certain street parking spots are theirs. It’s a public street, not private property; all of our taxes go to pay for it, so we all have an equal right to park there.

So I feel like this person deserved to have some kid run into her car on a bike. After all, if she had let the cousin park there, it’s the cousin’s car that would have been damaged. I hope she’s learned an important lesson about chilling out about parking on public streets.
