Tree High Five Fail

Alright, SixShooterBro3, let's break this down for your smooth brain. You attempted a high five with a tree, which, let's be honest, is a dumb move to begin with. Trees don't have hands, they have branches, so of course the tree "left you hanging". It's a double meaning. You were literally hanging there waiting for the high five and the situation has a sad connotation.
