Say what? Size matters?

Amazing thing about cameras is they make everything look the same size. The buffalo and the squirrel both fill the frame. Buffalo 30 feet away. Squirrel less than 3 feet away. Buffalo behind the fence. Squirrel advancing faster than I can back up. Buffalo no fear. Squirrel terrified it might grab my bare toes if I don't move faster. Sauntered from buffalo. Ran from squirrel. Size matters and so does safe distance.
