Benji says,

"Mom, look in my hair. There's something in my hair."

"What is it?" I ask, looking. "I don't see anything."

"There's something there. Right there. Look.  See?" He said.

"I don't see it. You're fine," I said. "What was it?"

"A gray hair," he replied earnestly. "You'd better cut it."
