We've had a Christmas party in KS2 this afternoon. Children were asked to bring some food to share eg crisps, biscuits, cakes etc.
So many children sulking because the food was put together, children actually saying to staff "I want my own food, I'm not sharing" massive bags of Haribo and crisps, boxes of muffins (32) which were sent to share between a class of 31 and the child wanted them for him and his friend.
I have never known anything like it in nearly 30 years of teaching.
