I think I may be irrationally angry so happy to be told I am being unreasonable.
The neighbours that back on to us had a lovely tree, which on returning home today they seem to have cut down. That, while sad, isn't my AIBU, however there is a giant branch currently laying across the back of our garden which has obviously been cut and just fallen. Recently we have removed our back fence (as it was falling down) and are getting it replaced tomorrow/Saturday. The neighbours don't know this as there is a thick bush on their side which you can't see through.
If there had been a fence in place it would have been destroyed by the falling branch, and I think what I am most irritated by is that they didn't even think to mention that they would be cutting the tree down or take measures to ensure that our property wouldn't be damaged. Plus we now have to chop it all up and dispose of it 🤬
I'm not going to say anything but AIBU to think their approach has been pretty inconsiderate (and want to chuck the branch pieces back over the hedge?!)
