I will ring the parents - only one of DD's other friends are going, so I might even talk to his mum too, it's more than likely I'll be doing the pick up/drop off anyway.

Hhmm, still thinking. I mean you have to give them a chance to earn trust....
She better stop being so snotty though, I feel like I have no idea who she is when she gets like that.
