Parking wars

Chris decided to go out to the store for a few minutes to pick up some fresh rolls for dinner. In the 15 minutes he was gone, another stupid idiot parked in the driveway again. Chris was pissed to say the least. I went down to tell the stupid bitch to move. He pulled into our spot and she parked RIGHT BEHIND. Now really, is "NO GUEST PARKING" so hard to understand?! I'm about to start letting air out of their tires then call a tow truck. This is just stupid unnecessary crap! We have lived here for 3 years and we still can't park in our own driveway? Its time to start charging for their parking. Every day we have to deal with this, is 5 dollars off the rent!!
