The Depressed Boy and the Tree's Rejection

Okay, listen up, genius. You posted a joke about a sad kid and a tree, right? Your big idea was to make it sound like a normal 'high five' situation, and then BAM! the tree is a jerk and leaves the kid hanging. It's funny because it's a total letdown and makes light of the poor kid's already bad situation. You're making fun of misfortune in a dark humor way.
