DS has been off all week with tonsillitis. Another friend has told me that her son in the same class has been invited to a party by a class mate. As they are not good friends I have assumed it is a class party with everyone invited, however we are minus an invite as he was off. I don't want him to turn up on Monday having missed out, but mum of party boy is very stand offish and hard to like and school is now closed, I could text her, we have a shared contacts list, but is that too cheeky? What to do?
