"It takes a pretty big mirror to see the big stuff like wings clearly enough, but you can use it to watch the smaller stuff, yeah, good thinking. Unless you have a wall-sized mirror at home which you can conveniently haul out to the beach for some firebending practice, I guess I shouldn't assume. Katas are a fine idea, not alarming your fellow dancers is very kind of you, it is as always a pleasure to teach someone who is both clever and methodical."
