Went to a party yesterday. They had a pinata swinging from a tree. The boys queued up to bash the thing with a big stick. It was a full on display of testosterone and agression (not just from the children tbh) and I was a bit shocked by it. The birthday boy and most of his friends were 4. Some of the younger children were really upset by it - couldn't understand why they were beating the living daylights out of the pretty horse in the tree.
And then the mother complains that starting nursery has made her DS badly behaved and fighty 
AIBU?
