Some kids just get under your skin, you know? You just love them to death, whether they're related or not.
Our neighbor has a little boy who's just precious to us. Is it because he seems to enjoy coming to visit us? Is it because he's so bright? Or perhaps it's that impish smile he gets every once in a while?
Ah, what greater joy is there than a child? We gave this little guy a small windup toy and he just shreiked with delight every time it popped over. You don't see that abandonment to joy among grownups.
