I was at the zoo with my girlfriend in the reptile section. A little boy was staring into the same tank that we were, his mom was maybe ten feet away. You know how reptiles are, they are always hiding behind some rock or branch or just blending in nefariously. So I ask the boy, "Do you see the snake?" It felt awkward to ignore another human being crowding around the glass with us and I figured I would give him a chance to feel good by showing off his superior reptile-spotting ability.
He seemed shocked that an adult he didn't know would talk to him. There's something weird about that being weird.
