The reasons why we do things are not linear, are they? For example, I keep my thermostat set pretty low in the winter to save money. My windows are drafty and need to be replaced. I can’t afford to replace them. Sitting on the couch by the window is a chilly affair. So that’s why I’m buying the curtains – they are thick and should keep out a bit of the cold. It’s not about looks, which would seem like a reason. No, it’s about shivering on the couch.
