My boots were so heavy that I was glad there was a column underneath us. How could such a lonely person have been living so close to me my whole life? If I had known, I would have gone up to keep him company. Or I would have made some jewelry for him. Or told him hilarious jokes. Or given him a private tambourine concert.
It made me start to wonder if there were other people so lonely so close. I thought about "Eleanor Rigby." It's true, where do they all come from? And where do they all belong?
What if the water that came out of the shower was treated with a chemical that responded to a combination of things, like your heartbeat, and our body temperature, and your brain waves, so that your skin changed color according to your mood? If you were extremely excited your skin would turn green, and if you were angry you'd turn red, obviously, and if you felt like shiitake you'd turn brown, and if you were blue you'd turn blue.
Everyone could know what everyone else felt, and we could be more careful with each other, because you'd never want to tell a person whose skin was purple that you're angry at her for being late, just like you would want to pat a pink person on the back and tell him, "Congratulations!"
Another reason it would be a good invention is that there are so many times when you're feeling a lot of something, but you don't know what that something is. Am I frustrated? Am I actually just panicky? And that confusion changes your mood, it becomes your mood, and you become a confused, gray person. But with the special water, you could look at your hands and think, I'm happy! That whole time I was actually happy! What a relief!
