Each morning when my seven-year-old daughter wakes up, the first thing she asks me is how cold it's going to be. If I tell her a specific number like 50°, she looks at me as if I asked her to solve an algebra equation. The next thing out of her mouth is, "do I need a jacket or not?" That's all she really wants to know; weather from a child's perspective can be distilled three basic things – shorts or pants or jacket. I think a lot of us are like that when it comes to the weather.
