Some wise advice

Waveboy started his second session of karate today, and he was one of two returning students in his class. The teacher (or sempai) likes to remind all of the students about where it is OK to do karate and where it's not. The dojo? OK. The playground? Not OK.

Today she asked the students if it was OK to do karate on the roof. The class answered "No!"

And Waveboy added, "If you do karate on the roof, you might not focus on the edge."

Well said, Waveboy. Well said.
