Rude neighbors

Now, I know of a branch of a tree is overhanging in the neighbors yard, they have every right to trim it back. But THIS particular neighbor doesn't even bother to inform us, so we can make sure the debris they will be dumping into our yard doesn't crush/damage other foliage (like the small orange tree with ripening fruit).

Like it would have been any skin off of their noses to let us know?
