They like it a lot if you reallllly mean it. Put the crown (top) of your head on a grandfather/grandmother tree while you are also "hugging" it for a feeling like no other.
It's got no arms, it couldn't have hugged you back. it's got no brain either, so even if it had arms, it still probably wouldn't hug you.
I've cut down quite a few trees and then burnt them but I've never hugged a tree who the fuck would do that???
