“Ah, you are a shrewd one,” the old man says.

“You’ll try to get two loaves of bread, rather than settle for one. Well, I’ll show you one other time, and, if you don’t like it, just say so, and I’ll return you to your own time, if there is time to do so. Take the tunnel to your left.”

You follow his direction, walk through the tun- nel, and come out onto a city street. Instantly you realize there is a war going on. Bombs and rockets are exploding all around you. You cry out to the old man, asking to be returned to the Cave of Time, but there is no time left.
