In tonight's class, for the first time in the few years I've been practicing Taekwondo, I momentarily lost my temper with a fellow student. Losing my temper is something I rarely do in any situation but there's a time and place for everything, and, to me, practice is not the place to be screwing around, especially for those of us on the Black Belt cycle, and especially from a student who's a higher belt. Blue belts and up should be setting the example for the lower belts, not playing around in class. I talked to the student after class, and hopefully we won't have a repeat of this incident.
