"Just Checking out the Dark"

The other night, we got home right as it was getting dark.  Instead of going into the house like usual, Gavin started walking out to the street.  I asked him what he was doing and he said,

"I just checking out the dark."

And he kept walking.  When he got to the street, he looked around and said,

"Yup, it's dark.  I need to go to bed."

What a cute little guy he is.
