What's Missing?

As the day started I was running full-tilt. I’d gotten up early and had already worked several hours before school began. As I hurried out to greet students, I failed to turn on the hallway music. While greeting kids in the hall, I realized that there was a strange quiet in the halls.

The next student to greet me was a second-grade boy. I said, “Hey there, Sonny, what’s missing this morning?”

He shot back, “My tooth! I lost it last night at 9:48 p.m.!”
