Okay, I am attempting to show a video of Everett laughing while we were driving through San Francisco. Hopefully this works. It is sponsored by YouTube. He was hysterically laughing due to sheer exhaustion. I kept making noises like "boo-psst" and he loved it. Sophia managed to get him to laugh several times like this by imitating me. He is about 5.5 months old here. Too CUTE!
