The other night Art accidentally rammed into Lewis, knocking him over. This has happened before, and Art was immediately apologetic, but while Lewis screamed and cried Art got down to Lewis's level and showed him what had happened (a tactic Ben has always used to distract the kids from their distress) and then, as I have also suggested before, Art offered Lewis a hug but THIS time Lewis said yes! So Art gave a crying Lewis a lovely, long hug. And since then they have been hugging up a storm. Here's a pic of a mobile hug Lewis requested in the kitchen. It went all the way into the dining room.
