When I was in kindergarten our teacher was trying to explain that there are four seasons in each year, each three months long and starting on a set date, such as winter starting on December 21st. The thing is, this was in the Canadian prairies, which are hellishly cold, even for Canada, and I remember getting into a huge argument with the teacher because in reality, winter (at the least) started in mid-October and went until early April. I remember trying to argue that if October was really in the fall, why did we have to wear parkas over our Halloween costumes?
