One time only

Two days ago, a student who had not done one ounce of work in my class and who talks continuously regardless of all punishments, worked. I knew he might because we were playing a jeopardy-style game about early civilizations and he likes competition.

And then nothing. I had even called his mom to tell her he worked that day. I did tell her I would call her again if this seemed to have been a "one-time-deal."

Not looking forward to that call.
