What is the most blatant denial you have ever seen in other mums as regard their children's behaviour? A boy once came running up to my DS in the playground and whacked him on the back so hard he almost fell over/ran off laughing.. I was fuming and when I confronted the mum (as she did absolutely nothing to tell him off), she said oh he was probably just saying hello, uh, WTH? This boy runs riot in the mornings and his mum just laughs it off, no wonder he is like he is! What are other mums' experiences? Thanks.
