Sounds like you are having a lovely day Oooggs!
Meant to say earlier to Caz - tempting though it is to tell them to stuff the gifted and talented day, there's probably no benefit to your DS by doing that, and it's unlikely to change anything, so unless you think he'll be upset / confused by going to a day there when it's not where he's going, it sounds like it would be a great opportunity for him to go to.
