The use of wit exudes a confident understated guidance while symbolically setting limits.
Hurtful humor has no place in the school house.
Keep in mind that we wish to gain compliance and communication, not dominance. We want to connect personally with our students, not detach them from us emotionally. Hurtful commentary destroys them. Go beyond the smile these bring to your lips. Analyze the wit, the thought, the guidance, and structure of the humorous comments so that you can start to employ this technique.
