My eye on you

Isnt he simply adorable??

Ever have that feeling when you're sitting in a cafe or just waiting and looking out in a traffic jam, to feel that there's a pair or eyes, or even eye, on you? And there's no shaking it off? It can be a physical pair of eyes, sometimes spiritual. Ghosts? Hmm....but spirits? I'd say so. Good spirits and evil ones too. And it can be rather... umm...shall i say, disturbing. And there's always that wonder that those pair of eyes are thinking. People stare (for all different reasons :P). May not be the most comfortable if you are the stare-ee. I wonder what it is about humans that give us the ability to sense this. That we dont need to watch to feel that we are being watched. It is the spiritual side of us? Something wired in our brains? What is it? 7th sense?
