I kinda know what you are going through. I live in a townhouse and share a common wall. My next door neighbor that I share a driveway with lets her kids play basketball on her driveway. I'm afraid to park in my driveway for fear that my car will get damaged and if anyone is visiting they have to park on the street because they don't want to get their car damaged. My dog goes crazy when she hears the ball hit my garage door or the ball bouncing in the driveway. Growing up my mother never would have went for this. She would have set up the backyard for us to play ball. When I first moved into my house I didn't know the local teenagers used my backyard as a cut through. When I heard and saw them on the side of my house, I quickly put locks on the gates.

I'm sure you are not the only annoyed by this.
