Outer London state primary [lots of affluent parents but also plenty who aren't], yr 3 kids. Matinee of a [fairly popular, fairly new, child friendly] West End muscal. The trip costs parents £50 per child. The school coffers may even be topping up these contributions a little bit [e.g. to pay for transport & for helpers]. As I understand it the tickets were block booked in advance [of the trip being announced] for the entire class. As with all these things parents can announce that they're not paying, but with prebought tickets the money will have to come from somewhere. All the kids want to go of course. As it happens we can afford it easily enough but I know that plenty of other families can't.
I'm mulling over a stern letter to the head. Reasonable or not?
