Mrs Hyde has been trotting out the same speech for years, I think.
Yes, I do think she's trying to put people off and I wouldn't like my DDs to be on her bad side, but we had her for my DD2's interview and she was lovely. She also sees quite a bit of the girls as they move through the school and the 6th formers seem to adore her.
She's South African and very matter of fact, and they are strict about RE/ Sex Ed /homework and no holiday in term time but so far the school has definitely been a good choice for us. We weren't that fussed about the school until we went on the open day, and I can see that it's not going to appeal to everyone so if you see something you like better, you should move WGGS further down your list of choices.
They always seem to have plenty of applicants.
