My Hair is Like a Barometer

You know how some old people will tell you that they always know when it's going to rain because their knee gets sore, or that it will snow because their fingers swell? Well, my hair can predict the weather, too. Yeah, yeah, so it's not a superpower, and it isn't even a unique ability. But there is a direct correlation between the level of curl and the chance of precipitation, and that is enough to help me decide whether to pack an umbrella in the morning.
