Rain
As far as I can remember I always loved rain. Whenever it rains, I feel content and at peace. It's like it washes all my negative feelings away.
The rain is noisy, but not too noisy. It knocks against my window, but its sounds don't intrude into my mind like, say, television or people's yelling do.
There's also something about the way the sky looks just before the rain, too. Maybe it's the melancholic mood it gives off, I don't know.
Sometimes I'll just open the windows and reach my hand out to feel raindrops. I never do it for long, though, because the rain is cold.
I love rain.
