I'm going to keep the parking space to myself.
What would you feel if you didn't keep that space?
I will feel bad about it and may have a hard time finding a new parking space.
Public parking space needs to be shared to everyone. If you want to keep it, your car should never leave the parking slot.
You should chill out, this is our space.
Unless you literally own the space, you can't claim it as your own.
