the world doesn't matter

What is it about rain that I love so much? There's a nice storm right now. I just spent the past fifteen minutes just standing in it. Just me. Singing. And I don't know what it is.. I mean I wouldn't usually go out in the middle of the night just to sing, but when it's raining, it's different. And I'm soaked but I really don't care one bit. I'm wrapped up in a blanket, soaked. What is this? Why am I so happy right now? I couldn't tell you. But I'm just, exactly, happy.
