The smell of (future?) snow

 It often happens, come November: the air cools down dramatically and suddenly I start smelling something in it. Something that isn't here. I am talking of the smell of snow. I know it must be wishful thinking: it's much colder this month, but we are still ten degrees to warm, give or take, for any snow drop. Yet I can smell it, especially at night. This is something quite distinctive about November: it is still autumn, but winter is coming and, to a degree, already there. Sometimes I consider the second half of November a de facto winter. Be that as it may, it is one of the reasons why I have started loving this month. But if it snows in November, here, in the South of England... Well, that would be highly unusual.
