I have a rival for Mommy's affections. No, not Bosco, whom I have complete control of, and not Daddy, who leaves me alone with Mommy most of the day. It's a rectangular silver thing, and Mommy devotes all her time to it, playing finger games with it and sometimes connecting it to wires that taste good. Mommy's very protective of this silver thing--she hurts my feelings by shouting NO when I try to nuzzle its shining face, and she carries it around in her arms lovingly, just like she used to carry me when I was a puppy.
I think it's called a baby.
