I have to ring school and tell them so they can decide what to do. I only know the girls first name but its quite uncommon so I think they'll work out who it is.
But if I ring the head of year and say I don't want the girl to know its come from me/dd will they respect that? I don't want the girl getting cross with dd. there's quite a few girls who know about it apparently so the girl won't know it must have come from dd.
