I've a slight case of paranoia, always checking the shadows in the corners of my eyes, perking up at the smallest sounds, and moving quietly so as to tell if someone's following me, while not giving away my location to anyone else. Sometimes, clouds and shadows get the best of me more than once, or the sound of a cat fills the silent night...

Here's a cloud at night covering the moon... laughing at us as it merrily watches us and our quick-paced lives, forgetting to relax, in case someone really isn't there. Or just trying to mess with us, and make us think there is.
