It was Miss who first figured out how that might best be arranged.
("Miss" was what Andrew invariably called Melissa, not because he was incapable of pronouncing her first name but because it seemed improper to him to address her in such a familiar way. Amanda was always "Little Miss"-never anything else. Mrs. Martin-Lucie was her first name-was "Ma'am" to Andrew. And as for Gerald Martin, he was "Sir." Gerald Martin was the sort of individual whom many people, not simply robots, felt most comfortable calling "Sir." The number of people in the world who called him "Gerald" was a very small number indeed, and it was impossible to suppose him being "Jerry" to anybody at all.)
Miss quickly came to understand more than a little about how to take advantage of the presence of a robot in the house. It was a simple matter of utilizing the Second Law.
"Andrew," she said, "we order you to stop what you're doing and play with us."
At the moment Andrew was arranging the books in the Martin library, which had wandered a little out of alphabetical order, as books have a way of doing.
He paused and looked down from the high mahogany bookcase between the two great leaded-glass windows at the north end of the room. Mildly he said, "I'm sorry, Miss. I'm occupied at present by a task requested by your father. A prior order from Sir must take precedence over this request of yours."
"I heard what Daddy told you," Miss replied. "He said, 'I'd like you to tidy up those books, Andrew. Get them back into some kind of sensible arrangement.' Isn't that so?"
"That is exactly what he said, yes, Miss. Those were his very words."
"Well, then, if all he said was that he'd like you to tidy up those books -and you don't deny that he did-then it wasn't much of an order, was it? It was more of a preference. A suggestion. A suggestion isn't an order. Neither is a preference. Andrew, I order you. Leave the books where they are and come take Amanda and me out for a walk along the beach."
It was a perfect application of the Second Law. Andrew put the books down immediately and descended from his ladder. Sir was the head of the household; but he hadn't actually given an order, not in the formal sense of the concept, and Miss had. She certainly had. And an order from a human member of this household-any human member of the household-had to take priority over a mere expression of preference from some other human member of the household, even if that member happened to be Sir himself.
Not that Andrew had any problem with any of that. He was fond of Miss, and even more fond of Little Miss. At least, the effect that they had upon his actions was that which in a human being would have been called the result of fondness. Andrew thought of it as fondness, for he didn't know any other term for what he felt toward the two girls. Certainly he felt something. That in itself was a little odd, but he supposed that a capacity for fondness had been built into him, the way his various other skills had been. And so if they wanted him to come out and play with them, he'd do it happily-provided they made it permissible for him to do it within the context of the Three Laws.
The trail down to the beach was a steep and winding one, strewn with rocks and gopher-holes and other troublesome obstacles. No one but Miss and Little Miss used it very often, because the beach itself was nothing more than a ragged sandy strand covered with driftwood and storm-tossed seaweed, and the ocean, in this northern part of California, was far too chilly for anyone without a wetsuit to consider entering. But the girls loved its bleak, moody, windswept charm.
As they scrambled down the trail Andrew held Miss by the hand and carried Little Miss in the crook of his arm. Very likely both girls could have made their way down the path without incident, but Sir had been very strict about the beach trail. "Make sure they don't run or jump around, Andrew. If they tripped over something in the wrong place it would be a fifty-foot drop. I can't stop them from going down there, but I want you to be right beside them at all times to be certain they don't do anything foolish. That's an order."
One of these days, Andrew knew, Miss or even Little Miss was going to countermand that order and tell him to stand aside while they ran giddily down the hill to the beach. When that happened it would set up a powerful equipotential of contradiction in his positronic brain and beyond much doubt he would be hard pressed to deal with it.
Sir's order would ultimately prevail, naturally, since it embodied elements of the First Law as well as the Second, and anything that involved First Law prohibitions always took highest priority. Still, Andrew knew that his circuitry would be stressed more than a little the first time a direct conflict between Sir's decree and the girls' whims came into play.
For the moment, though, Miss and Little Miss were content to abide by the rules. Carefully, step by step, he made his way down the face of the cliff with the girls in tow.
At the bottom Andrew released Miss's hand and set Little Miss down on the damp sand. Immediately they went streaking off, running gleefully along the edge of the fierce, snarling sea.
"Seaweed!" Miss cried, grabbing up a thick brown ropy length of kelp that was longer than she was and swinging it like a whip. "Look at this big chunk of seaweed, Andrew!"
"And this piece of driftwood," said Little Miss. "Isn't it beautiful, Melissa?"
"Maybe to you," the older girl said loftily. She took the gnarled and bent bit of wood from Little Miss, examined it in a perfunctory way, and tossed it aside with a shudder. "Ugh. It's got things growing on it."
"They're just another kind of seaweed," Little Miss said. "Right, Andrew?"
