You’re next
Dads come up with the best (worst) jokes of all. It could be a pun that you’ve heard a million times or a fresh joke that your dad made up on the fly. Whatever it is, we know that you’re groaning inwardly while not admitting that you actually want to laugh at the joke.
Here, this person texted their father from the bathroom, alerting the dad of the dangerous moth situation taking place right outside the door. After the dad went to investigate, the moth took his life and replied to the child’s message. “You’re next.” At least the moth sent the text with love.
