There is a rock on my dresser. From where I am sitting on the couch, I can see a rock on the bookcase in the hall. There is a rock on the kitchen table. There are several in the car. Everywhere we go, Duncan needs to pick up a rock. "It's for my collection, Mama." I have read that three is the age for this kind of thing, and it's interesting that the desire to amass objects of a similar kind can begin so early. I suppose it could be worse than rocks. It could be yarn or shoes...or Vera Bradley bags.
