First real interaction with our Neighbours-to-be is to discuss why a tree of ours has fallen and crashed into/onto his tool-shed, this incident swiftly let to a series of calls from other neighbours bringing various other nature related issues, such as termites and dead looking trees… I hope this isn’t a sign…
Previous tree incident below from June last year also led to an interesting discussion with a surprisingly forgiving neighbour, yes that 10 meter tree is dangling over his house!

why do you always have a problem with trees at your houses. do previous owners leave the place booby trapped.
well strange you should say that!
The neighbour who received the tree in his garden so graciously had told the previous owner that it was dead and a liability and he apprently said “well that’s a problem the next guy can solve”, booby trapped indeed!
