(Me)- Nah bro, I'm a Glow Stick cuz!
(Guy)- How?!?
(Me)- If you broke my arm, shook it real good, and turned out the lights, I would glow red!.!
The transformation from an awkward ugly duckling to a confident majestic swan...who will eventually bang anyone in an attempt to cement their glow-up status and make up for lost time.
