I hope everyone had a happy Easter!
This conversation between Rex and Frank is an indirect way of me saying how I feel about how easily we tend to ignore the real meaning of things and only think about ourselves. I think we all need to be a lot less selfish and prideful and a lot more kind and willing to listen to the hearts of others. Listening is a skill we all need to be better at.
...I also wanted to show how innocent Rex really is. He's just a giant kid at heart. And like many of us, might want to help others but just may not know how. Rex simply resorts to what he knows best... food.
