Welcome to four!
Luke talks more and more about being four (and me being "thirty-thousand") and what it means. Until he turned four, THAT was gonna be the age at which he was old enough to ride roller-coasters. He's since changed his tune and said that five was the right age for that madness.
But my favorite stuff is when he doesn't so much talk about age specifically, but about "being a daddy." The privileges that apparently come with fatherhood are vast: he'll get to "drive the van," he'll get to shave, he'll be tall, he'll be able to jump up to the sky. But my favorite daddy bonus that he's talked about looking forward to? He'll finally get to have his "own boy to take everywhere." You bet, Luke. It's one of the best perks there is.
