Getting colder

It's a good question - did I notice that I had cold morning breath this morning (as opposed to morning breath which is quite quite different - although hopefully this is never so bad you can actually see it) because it is colder or because this was the first cold morning where I was talking to myself in the car (about the state of the windscreen clarity in the car in front of me - especially as it was being hit by the morning sun)? In any case, it is cold - but not so cold that we've had our first frost yet.
