Dear Jon, Jeremy, Josh,

I will likely not be able to make coming Thursday's class due to a
workshop I have to attend.

Could one of you step up to teach?

To all co-students - if none of the black belts can make it, class will
still take place, led by an advanced student (TBD).

Whoever teaches the class, please be reminded to be out of the room by
6:15 PM sharp to avoid trouble with the following group.

Thanks a lot!

Osu, Kai
