Walk the Line

My mom drove us to dinner one night, and she parked diagonally in the parking spot. I told her that she should move her car, so she did, with this being the result:

She was still in the driver's seat so I tried to get her to re-park again.

Me: Maybe you should try again, you're on the line.
Mom: I'm in the line!
Me: No you're not.
Mom: Yes I am.

Then she walked around and saw her parking job.

Mom: You are my constant critic!!!

Then she spent the rest of the walk to the restaurant pointing out everyone else's crappy parking job.
