This has all come about because the local state schools are touting for business - the other day the entire year group went to the local Catholic secondary school for the day, and it was universally hated. (Incidentally this isn't the one we have planned for her.)
I think (and that's a very big think) we could just about scrimp and make sacrifices to send her to the cheapest one, but with dds 14 months apart there's no way we could afford to send both.
I've explained the money thing but it must be very hard for a 9yo to understand, when all of her friends are going that way. She just seemed very worried, particular since she's heard about her Y7 cousin having his faced pushed into a wall at the one we have planned for her, and breaking his tooth.
