You know the saying "Don't cry over spilled milk"? Well, you can relate that with the above statement. There's something so very nice about a person who can get wet and not complain. Afterall, it's only water. Water dries and so does your personality when you bitch and complain about some moisture on your skin.
Walk inbetween the rain drops, kiss under the falling droplets, and splash into puddles. Say "Yes!" to oppportunities and "No!" to people who are plastic.
Perspective can change everything, including a drab rainy day. Be the colors you want in your life.
