Health and safety gone mad

Took my 7 yr old to school this morning the roadswere damp as it rained last night, got in the playground and some boys started to have a kickabout before the bell went when the teacher came rushing out of her classroom shouting you can't play football the balls to wet and might hit someone.I remember my school days thats all we done before school breaktime and down the park afterwards (jumpers for goalposts).
