Multiple Regrets

I have an emergency and am unable to make Thursday's call (Sept. 2).

 

(Appologies for late notice, a minor medical emergency - my son - and
Thursday morning is the only time this week the doctor can see us.)

 

While I'm at it, I will be unavailable the following Thursdays (don't know
if there are calls or not):

 

September 9

September 23

September 30
