Concord Grapes for Breakfast

I served Concord grapes for breakfast. Big mistake. You would think Bow would enjoy a change from the usual green or red table grapes. But no! They have seeds.   He won't eat them. He goes without eating breakfast and is planning on being grouchy and impossible to deal with for the rest of the day.

Where is it written that a common chimpanzee has to have seedless grapes every morning? Why does he think this is worth ruining the day over?

"Bow, aren't you hungry? Why won't you eat your grapes?"

He spells: "They are so very bad!"
