Sometimes Chester just does stuff, and Greg and I will both be watching him, giving each other that look that says, "Are you seeing what this kid is up to now?" Usually Chester is so involved that he fails to notice us both watching him. Then eventually he stops and looks at us both smiling and silently laughing at him. After one such episode the other day, when he finally looked over at me I said, "Oh Chester, you are a delight!" Then he promptly threw his head back and pointed at the light.
(He was stuck there and I just had to take a photo before rescuing him.)
