Our current neighbours are wonderful - a policeman and classroom assistant wife on one side, a chest specialist and classroom assistant wife on the other.
Our previous adress had council allotments on one boundary and we fell out with the 'secretary' who was a real Napoleon type.
He reckoned gaps in our fence was letting in dogs which fouled the allotments, so one day, he arranged for the council to take away our fence and replace it with chesnut paling.When I complained to the council, they said that the 'Secretaary' had sought and obtained our permission!
I advised them that he had not done so, they had trespassed and destroyed out fence, and I looked forward to the replacement of sixteen panels of fencing (the border was the entire side boundary of our house and front and back gardens) or I would call on our adjoining neighbour who had witnessed the incident and sue them in court.
The fencing was duly replaced, free of charge, and 'Mr Secretary' never spoke to us again until his death a few years later.
I don't believe in neighbourhood disputes, but I detest bullies and jobsworths as well, so if someone wants to start trouble, I will always finish it.
