am holding party in a small hall,as have pets and lack of space at home. I decided that 25 was a manageable number, by the time I invite cousins etc, that only leaves 15.So I asked dd who she wanted to invite and came up with 15 out of the 28 in her class. Invites went out friday, and today I had one mum come up to me and say that this is unfair and if it is a party in a hall, the whole class should be invited.
