Having had trouble with neighbours in the past, I now realise it was not just us, whose lives were made a misery - seems bad neighbour relations is quite common. My neighbours complained to the council all the time about us and our animals, and all sorts of things. The council in the end said the complainant definitely had a problem - and it wasn't anything to do with us. They even sent the gas people round, as they said they could smell gas from our Rayburn?
Man tested the gas, and said he could find nothing amiss on his gas tester, and could not smell anything. We had to rebuild our garden wall, that supposedly was about to fall on the neighbour, who was 20ft on the other side of the fence, replace roof slates, which the builder could not see were even off, etc. etc.
Some people have nothing better to do than complain. I wonder what they would do, if the same happened to them though.
