I used to love the rain. Puddles and rainbows and umbrellas; they're so much fun. Plus, rainy days were sort of rare when I was a kid. Rare things are easier to adore than common ones.
Living in Germany changed things. Going for more than a month without seeing the sun even one time . . . that undid my ever-since-I-was-little preference for cloudy, rainy gray.
These days, I don't love rainy days more or less than their sunny opposites. They just are what they are and they're both good.
