So I said to him "Why can't you just be nicely behaved and, well, normal like the other six year olds we know?"
and he said "It's really hard being six"
and I replied "Well you should try being the parent of a six year old"
and he said "It's just a difficult age"
and I replied "Just wait til you're nearly 41 like me"
I'm not sure that he learnt anything and I'm not sure about my parenting skills but hey it put me in a better mood.
