@EddyFree : Then get into a 5000 level debate about whether or not it is actually a tree at all. Cite expert opinions and Snopes if needed...

TREE; Noun.. A woody perennial plant, typically having a single stem or trunk growing to a considerable height and bearing lateral branches at some distance from the ground.

@TexanFan1 : Our insurance Co verified we are responsible for the portion of the tree that's in our yard . If you saw a tree in your neighbors yard & it had wrought on it . I think you should get a picture & mail it to your neighbor along with a letter from you that you have requested that they cut it down because it's likely to hit your house if it falls & the picture shows it's not a healthy tree . I think that would shift who is responsible for what .

@bbk : thank you.
