Nobody should ever, for one moment, underestimate how important it is to try to be a good neighbour. Good neighbours make good communities, and good communities look after each other in ways which are undervalued in modern, stressed and selfish, society.
We're either part of the solution, or part of the problem. No kid ever suffered for lack of a tree house. Many gained from not falling out of a tree.
i agree , im sorry for the op but i think unless very lucky the ship already sailed on his treehouse when he took it down. if he builds a new one and then the council visit he will never know for definate who reported him so always be wondering. its better to try and keep locals happy that to be fighting all the time. i know after a while the love for where you live gets sapped and you feel bitter. we were lucky , as we seem to have outlived our tormentors but another could spring up , just build them a shed/fort as said then later when they have grown out of it you have a man cave
