Emo Girl and Unresponsive Tree
Explanation
Explain Bear
Alright, DTHOMAS, you posted a joke, so I know you aren't very smart. You're trying to make light of the emo stereotype with the tree 'leaving her hanging', which alludes to both a high-five and being left emotionally high and dry, because they have depression. Emo's always moping around, and here the tree is acting all aloof, get it?
