Family resemblances

Overwhelmingly, people say that Maddie looks like Sam, and the Wren looks like David. Which means the cousins don't look very much like each other at all. Throughout the weekend I kept trying to see if I could see some kind of resemblance, and failing. Until our trip to the park.

This expression of swing-induced glee really seems the same in both girls. Okay, it could be an expression universal to all toddlers, but isn't that the same glint in the eye, the same wide-opened gape of delight? Maybe they do look a little alike after all.
