My youngest son is a very happy little boy.  He is usually smiling and often sings as we wander through grocery store aisles and in other public places.  He enjoys spending time outside and looking under rocks.  Recently, he has also started talking in his sleep.  This morning, as he slept, I heard the following words from him:

“Hmmm hmmm, here comes caterpillar.  Here comes it.  No, caterpillar.”
