Some years back, after starting the build of our house, I lined up the boundary markers. To do this I hacked back my neighbour's overhanging tree branches. When she came home she wasn't too happy and physically attacked me. My mother in law phoned the police and a policeman responded within 10 minutes. Upon my MiL explaining the situation to the policeman he ordered the neighbour to cut the tree branches back to the boundary markers and he waited the 2 hours it took for her to do the task. Hard for me now to say a bad word about Thai police.
