Roscoe has a distinct cry when he is hungry. When he's upset or otherwise unhappy with his state in life, he'll cry and turn different colors. When Roscoe wants food, he'll furrow his brow and look at us with a worried look on his face. He'll also take a pause between cries to see if we're going to respond. It's the first steps of communication with his mom and dad!
I'll look back on this video fondly when I'm in a conversation with someone and Roscoe stands by me, tugging on my pant-leg trying to get my attention with "Dad. Dad. dad. dad. Dad. Daad. DAAD. Dad. Dad!" (repeat).
