Well, she didn’t say how!
I’ll admit that she’s wound a little tight. When I was a teacher, I would have laughed and given it a karate chop myself. :-D
The first panel reminded me of my grade school years, in a Catholic school. Your typical preteen boys, can’t wait for recess, and get out, and start running anywhere, and everywhere. Good old Sister Joseph, when on playground duty, would tell us we could “skip, or, walk fast, but, no running.” Yup… tell a bunch of boys that were cooped up in school, that they couldn’t run (or had to skip?). That lasted until she turned around, and we went from a standstill, to zoom!
