I hear yesterday a lot

"Did you brush your teeth, Layla?" I asked.

"Yes," she replied.

Really? "When?"

"Yesterday," she answered, brushing the hair out of her face, "I brush my teeth, yesterday."

I could explain the difference between yesterday and today, but why bother.

"Layla, brush your hair," I called out.

"I did already," she responded.

I've just saw the little girl and that hair hadn't seen a brush. "When did you brush your hair?"

"Yesterday. I brushed my hair yesterday, Mommy."

A lot of things happen on yesterday.
