From way up in the sky the lake looked like it wasn’t deep at all, and that a brave dog could walk all the way across if he didn’t mind getting his socks wet. But now that we were at the edge of it, I could look into the calm grey water and see that it was very, very deep, and that the tiny islands that barely poked their noses out of the surface were actually very tall rocks standing up from a bottom so deep that I couldn’t see it under all that glowing grey water.
