He’s happy to meet this new person. In his short life, he’s been cosseted and played with and cuddled and asked to learn certain manners. He’s getting better about most of them. This new person has a different scent than the ones he’s known since he left his dam’s side. Where all the others carry the scent of the outdoors, this one does not. Her scent is that of inside. But as he investigates her more thoroughly, even going so far as to taste her skin, he understands that she is going to need his fun sense more than any of the other people in his short life. So he flops onto his back and pretends to bite her foot. He is instantly rewarded with that altogether marvelous sound of human laughter.
