We live in an end terraced house, there's a public path down the side, then a wall about 8` high, dividing us off from a new housing estate. We have a wall about 3 and a half feet high around our back yard, and the stones on the top are mostly broken off, because of, not just kids, but young men, standing on our wall in order to reach over and climb over the other wall onto the housing estate, it saves them a long walk round. We`ve been out and spoken to them, as well as banging on the window, but all we get is abuse. Some kids doing it ended up picking gravel up from the edge of the road on the other side, and throwing it over into our yard, plus sitting on top of the wall, picking berries off a tree that`s on the other side next to the wall, and throwing them into our yard as well. There`s not a lot we can do, if we go to the police they won`t be here when the police arrive, that`s IF they arrive.
