dd's 6th bday party today - for one reason or another 4 of the parents stayed (without prior warning). I don't know any of them at all, and when they asked if they could stay I said 'sure - as long as you don't mind being ignored by me' then offered them a drink and left them to chat with each other/their dcs as I hadn't expected anyone to stay. They were right in my kitchen while I was whizzing around preparing the food, dealing with the various crises (someone wet themselves and needed to change and borrow clothes etc etc). I didn't really offer them party food or anything, but as one was leaving they grabbed a few buns and said 'I'm starving'! So now I wonder - should I have offered them food? Tried to be more 'hospitable'? They could see I was crazily busy, and I offered them nothing beyond the initial cup of tea as I just had to focus on the party...
