One afternoon, while you were drinking water leaning against the kitchen, your robot approached you until he was just inches away. You swallow hard, but don't reprimand him - he's not doing anything truly reprehensible, after all. But then he takes your hand in his, raises both together until your palm is open against his. You watch in amazement and lips parted as he critically analyzes (lips in a straight line and gaze squinted in concentration) your hand in his, rotating the two to see the stark difference in size and texture. He squeezes your hand in his, feels the softness of your skin, the temperature... and then he gently releases it to its previous position. He looks into your eyes with a mischievous gleam once before leaving as if nothing had happened.

You don't know how long you stay in the kitchen after that. He touched you without any permission and that is wrong. But it's just curiosity. He's just curious about the differences between you two...that's normal.
