Is That Meta?

Last night, after being tucked in to bed, my older daughter came to the top of the stairs and called down to me.

"What?" I answered, assuming that there was some problem.

"My sister is going to tell on me," she replied.

"Wait. You're telling on your sister because she's going to tell on you?"

She paused. "Yes," she finally answered.

"Go to bed," I ordered, shaking my head.
