I happily accepted when they were cast as part of the "ensemble". (Happily accepted like the Toddlers & Tiaras moms do when their kids fail to make the final crowning.)
After the first rehearsal, I was given the lists of parent responsibilities. The parent responsibilities included:
Tuition *cough, cough, choke, gag, gasp, cough*
30 Volunteer Hours
Retaining a sponsor
Selling Tickets (to our friends and family v. just at a booth or window)
Here's the kicker - I have to work the snack bar as part of my volunteer hours and today I found out that in addition to taking the money and making change I'm supposed to provide HOMEMADE BAKE SALE ITEMS to sell as well. I have THREE snack bar shifts.
