Going for cold

 Our kids seem to be impervious to the weather. Even today, when the starting temperature was 11F (about -11C) the Girl would not deign to wear a coat as she strolled up the street to catch her bus, and the Boy's only concession to the cold was to put a sweater on under his lightweight hoodie before he cycled to school. Me, I went with the full works - snowpants, thick socks, lined boots, down jacket, woolly hat - and still felt chilled.
