Not sure what it is but keeps you wanting to be cuddled up with a warm cup of cocoa and a really thick blanket that you share with the ones you love,even if it wasn't that cold. It makes you want to bake, tasty fulfilling stuff that fill the house with the aromas of cinnamon, apples and brown sugar, regardless of all the guilt that comes with over consumption of that nasty white flour. It makes you want to rot in your flannel Pjs in front of the TV with reruns of old comedy shows that you know by heart, for some laughs and a lot of familiarity. Fog makes you want to do a lot of things..not one of them is coming to a lifeless job real early on a Saturday morning.
