#9....about two to three inches...because it was close to shore, and the thing I said made the person I said it to laugh with me and insult me back with a real good one, before we forgot about the rock, and the water, and went and had a cheeseburger because some people are not crybaby weaklings that need therapy or a safe space if I tell an off color joke in front of them, or randomly tease them about ugly boots or stupid ideas etc. if you sterilize the world, you'll end up with a bland, colorless little void of gray people with nothing to say to each other, all staring into a cell phone and waiting for instructions on how to think, feel, and act.
