At home time today I was letting the children out when a mum came up to me and said "who can I complain to?" I said the headteacher. I said what appears to be the problem? She said "one of the kids snuck past you and you didn't even notice, they could've gone home with anyone".
I asked her which child it was and she said "I'm not telling you I'm going to complain"
I mean honestly! It was a honest mistake that he snuck past and that I didn't see him. I would never want a child to go home alone/unaided
AIBU or is she? She went and complained to headteacher
