The Point of Dis-ment

I am disappointed in the turn my Adult Improv class has taken.  Every week, fewer and fewer folks are attending.  Last night- three.  I am enjoying the class, but if there aren't sufficient numbers to effectively do the class, we'll have to disband.  Sure that'll free up my Monday nights, but I need the growth.  I would much prefer the others to return over a refund.  As I said...disappointed.
