I think this all the time. Try going in pitch black with a picher of water, a flashlight, and a bowl. As you pour the water in to the bowl shine the flashlight across the water. It will move sightly with the light.
I know all of you have a heart. Even the ones that don't repost. Please everyone just pray for ppl with cancer because it's honestly so sad. Please repost, but if you don't you still have a real heart. EVERYONE has a real heart.
