Is it for show, or for blow?

We manage to sit down for dinner every night, though my boss would probably prefer that I stay at work a few more hours in the evening. I think it's an important time for us to sit together and talk about our days. Maureen is beginning to share with us and is able to tell at least one story about what happened at school. We manage to draw something out of Rowan through a series of questions, though we are never quite sure he is feeding us the facts.
One of my favorite parts of dinner is when I ask who needs a napkin. Everyone answers yes. I hand out the napkins, but hold Rowan's as the last. When I finally give one to Rowan, he holds it to his nose, makes a blowing sound with his mouth and then hands it back to me saying "Thank you." Then he waits for all of us to laugh. He knows he's funny.
We'll try to get this on video, though he usually clams up when we bring out the camera.
