To show children how to behave?
I was in a cafe earler where at the table next to me there was a 4 year old girl, her dad and her granny. She was being a bit whiney, nothing major but they were talking about how difficult she was (in front of her) and then the dad said "When she starts school it will improve as the teachers will show her how to behave".
AIBU to think this is the parents job - not the teachers?
