I hope it wasn't a complete bust

Hey folks,

Sorry about the poor learning conditions in Keith Hall today. I thought the jackhammer would end. Of course it stopped right after class. If I knew it would have been like that all class I would have cut all of our losses.

Anyway, I'll try to make it up to you somehow. And I've formally let the powers that be in the administration know that the working/learning conditions today were absolutely unacceptable.

Jack
