I've just witnessed my neighbour (18) walking across my front lawn (he does this frequently as a short cut) and spitting on it. I've shouted out the window and told him not to do it. I didn't hear his reply as shut the window but looked like fuck off or similar. This guy has no respect for his neighbours and we've had many issues over the years. When I've spoken to his mother she's usually tried to turn things round and make out I am unreasonable. My children play on the front lawn on a regular basis and I don't want them getting his spit on them. It disgusting.
