It's too early for philosophical questions

I'm putting dishes away out of the dishwasher. The girls are eating cereal and milk.

Fiona: Mom, can you come here for a minute? (I do.)
Fiona: Do you think his hair (Quaker on cereal box) looks like dough?
Jen: Now that you mention it, I guess his puffy hair could look a little like dough. Our hair is straight, but some people's hair is fluffy, and some people have curly hair. Some people have no hair at all.
Fiona: Why?
Nora: He can't take off his hat. Huh huh. He's on da Life cereal. (Leave it to Nora).

I'd better wake up. This may take a little explaining.
