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.
