I don't want to take this down a racial route, especially given my first posting. But as I'm simply recounting the innocent behaviour of kids.
I was a toddler travelling into London on the train. In the seat opposite was a black guy. I did the usual child; 'whisper' (AKA shout) to my Mother about the chap sitting opposite us, I had never seen a black person before and was confused. The poor guy had heard my shout/whisper and continued to mesmerise me by showing me the palms of his hands and the tops of his hands. A small child was completely mesmerised by the magic of changing colour hands.
