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.
Ok this is just hilarious! It's so true! Unless you are all muscle you feel so fat when you sit down! I always end up lifting my legs up, 'cause I can't stand it. I feel like everyone's staring at my legs!
