A Conversation Between my Little Brother and Sister

I laid in my bed watching television and my little brother and sister were doing their homework.

Ellis grumbles to herself and turns toward me, "Is there saturated fats in feces?"

"Excuse me, since when did yall start taking Bathroom 101 in high school?"

"You know, like oils and stuff. Is that in feces?"

Peter, my little brother walks in. "Saturated fats are like butter and shortening. Solids. Liquid oil is unsaturated fats. So are you asking if liquid oil or solid oil is in feces?"

I pull the covers over my face. "I don't remember learning about this stuff when I took biology back in my day. What happened to just learning about cells and what your fingernails are made out of?"

Ellis and Peter ignore me.

Ellis says, "Saturated fats, so I guess solids. Is that in feces?"

Peter nods, "Yes. Anything else?"

"Yea, have you gotten to that chapter about mammary glands and lactase versus lactose yet?"
