I did my self-control lesson two weeks ago (a summary is here and the complete lesson is in my book).

On Friday, I showed impatience with one of my students. Another student then called me over and said, in a respectful tone, “Don’t eat the marshmallow, Mr. Ferlazzo.”

I thanked him, and then went over to apologize to the student with whom I had been short.

It’s always a positive sign when students feel that they can critique the teacher….
