I over heard a volunteer mum (goes in one day a week to support reading etc) engineering the kids' friendships by chastising a girl for ignoring her daughter and playing with another. WTF! I am not often at the school gates and assumed all the social joy/pain was a result of kids bundling along not adults poking their nose in. The kid that was told off was not mine but I know her parents well enough. should I tell the kid's parents or am I then also guilty of being a nause?
