Rain = sadness?

Correct me if I'm wrong, but most of the people that I know LOVE the rain. Maybe I'm wrong, but all of those "AHHH IT'S RAINING!!!!" Statuses on facebook kind of gave me that idea. But here's a question for you. Why, if everyone loves rain so much, do so many songs and movies and such identify rain with  feeling sad? If you love rain, shouldn't rain make you happy? I've always been thrown off by this. I understand that rain kind of looks/reminds you of crying in a way, but still. If I'm sad and it's raining, it's only going to make me feel better :)

There's your random thought for today... :)
