John,

Red is not usually innocent (look at this one) but the red you sent me is! It’s the red of childhood. A pretend red. Or the red of young eyelids shut tight - the red you saw when you did that. As I look at it, I wonder what will happen when it grows older. Maybe it wouldn’t be red anymore at all. My guess is it might become black...
