No wonder they are looking in Nixy.....
My folks are in a similar situation. They share a long private driveway with a neighbour and have there own drive to park the cars. My folks drive is built to take 11 cars so is rather big. Loads of random kids come to cycle on the long drive but use their drive to swing bikes round. My Mum has lost it a few times as we all like our cars (mine is sometimes arked there when I'm away) and she is terrified something happens.
I like it when parents come to complain my mum has upset there kids. I've answered and explained that this is a private residence. They have go arsey so I've asked them to leave details so I can send the bill for damage to their house, or alternatively I'll come and play on their driveway!
Anyway, just tell the little sh*ts to F*ck off.
