Moved into my new house around 2 months ago. My back gate is always locked, I'm very security conscious. My neighbour I have said a friendly hello a few times but I don't really know him other than that (I prefer to keep neighbours at a friendly distance). Every so often he leaves his back gate open, this means anyone could have easier access to my back garden too as the gates are sort of connected. I assume he just forgets, don't see why else he would do it? He has two cats but they climb over it with no difficulty. So when he's not in I quickly run out and lock it! (I can just reach over standing in my garden, I wouldn't go onto his property). It also bangs when it's windy and it does my head in.
Does that mind me a weird neighbour? Should I just mind my own fucking business?
