Rex

An amazing, supportive friend. The best listener, an incredible person. He’s great at finding the silver lining. If you don’t have a Rex, you’re missing out. He’s the absolute best person. He knows how to cheer you up when you’re feeling down. He is funny, kind, and caring. Rex is a badass.

Rex is quite possibly my favorite person in the entire world.

Did you hear Ryan fell off the moving walkaway at the airport onto his head again and woke up screaming that the Pega-Rex was trying to eat him? I swear he's on drugs.
