You can learn a lot during a walk home from the village store when the temperature is zero.  Like, that coke in your coat pocket will do the same thing as the coke you put in the freezer at home.  And that a good quality Carhart coat which is waterproof from the outside in is also waterproof and coke-proof from the inside out.  And if you take your coat off really careful, and have a straw handy, you can still enjoy that coke slushy you made with just a little lint at the bottom.
