My neighbour had been parking her car in my designated parking space every weekend for almost six months. At first, I didn't mind because she said her husband usually came home late and there wasn't enough space.
Then it became a habit.
She would park there even when I was home, and whenever I needed my space, I'd have to call her to move her car.
Last Saturday, I came home and found her car there again. I politely asked her to move it because I had visitors coming.
She looked at me and said, "It's just a parking space. Why are you making such a big deal out of it?"
I didn't argue.
