Dd is in a 6th form production of Antigone, and year 7 ds is one of the child chorus. They are at different schools. So far rehearsals have been after school or at weekends, but I have just discovered that next Tuesday is an all day tech and dress rehearsal. All the other children are year 7s at dd's school- so it's not a problem for them. I am tempted to call in sick for ds, but I really, really don't agree with doing that. But what if I ask and they say no. Eeeeek. What shall I do?
