The Sweetest Gift- A barking dog?

So apparently, my little man was holding out on me. A few weeks ago I got him to 'laugh' a couple times by tickling his chin. By laugh I mean a Tyra Banksish smile with his eyes and faint 'ha ah'. Monday night however; we found out what his real laugh sounds like. We were sitting in the living room with a student who was visiting the university Micha works for. Her flight didn't leave for a few hours so we took her out to dinner. Before we left, we were hanging out and Lily the Destroyer was kind of bothering her. Micha, who had Charlie in his lap, got one of Lily's toys and she started barking. Charlie jumped at first and then, clear as day, laughed. Really laughed. It was the cutest thing! We were all so amazed that instead of telling Lily to shut up like we usually do, we encouraged her to bark away!
