Why not? It sounds quite a nice school. They took the time to show you round the school as an individual, showed you the classroom and you then had a talk with the SMT AND were concerned enough to ask you if you had any questions. I think you're <u>possibly</u> over-reacting here and being a bit over-sensitive, just because you weren't expecting such an individual session, especially if you've been shown round 'in bulk' before. Just think again, now you've gained a little distance. If you still say 'it's not the school for me', then it isn't and move on.
