I'm going to ask a USPS worker to re-do her parking
Why are you going to ask her that?
She parked pretty messed up in front of my house.
If it's not blocking your driveway or something, I wouldn't worry too much about it. The car is not going to be there long to begin with and she's just trying to get through her work day, you will just be adding extra time to her shift. It's only temporary so I would just wait for her to leave.
Why are you defending her so much?
Well if the park job is not causing an issue than it does not make a lot of sense for you to be upset about it. If she is blocking your garage fine, but if she is simply parked in a spot that does not prevent you from doing anything than it should be fine.
