Rock Collection

Some time ago, Brandt announced that he was done with diapers.  I was overjoyed and suggested that we clear out the drawer that housed the diapers.
"What will I put in it?" he asked.
"You could put toys or treats or your rock collection in it.  Anything you like," I replied.
Brandt was excited about putting his rock collection in it, even though he didn't have a rock collection.
Did not.
But now he does.  He has been collecting rocks from around the neighborhood, particularly from a house around the corner.  And he has put them in his drawer.

The drawers.

The rock collection.
