I don't remember my secondary school, an 8 mile bus trip away, ever being closed. And the village primary school, a one mile walk, never was. But this is something of a British obsession now. I think I have mentioned before, but a friend in Canada has a 14 year old. The girl complained that they had to go outside at breaks because the temperature was minus 18. Had it been minus 20 the pupils could have stayed inside. Can you imagine the fuss if schools here had a rule like that?
