well... as good as 'dancing in the rain' may sound, when it's raining or especially when it's snowing is perfect to spend some time with somebody. Whether it's gonna be your family, write a long nice letter/email to somebody close to you. Or ideally just with your beloved, to hold her, hug her and just look through the window and dream together, talk to each other about everything or just silently enjoying love, under the sound of the falling drops :)
