[Closed] Kids getting told off for stuff that I don't think is wrong

So eldest OAB went on first day visit to new secondary yesterday.
.
He met up with a bunch of other kids, some from schools with forest/trees as school grounds. He is encouraged to climb trees at home. His mates climb trees. The other local village schools allow climbing trees. I spend my time at work persuading teachers that kids should take more risks (like climb trees). I spent 15 years outdoors allowing kids to climb trees.
.
It cuts deep that he was told off at the secondary, then hauled back after school as he had 'let the school down' with 'reckless and dangerous actions' and he 'nearly killed himself'.
.
He was 4' up a tree with a couple of other lads at break.
