Gary may be reeling from the loss of his close friend, John, but it doesn't keep him from finding a reason to smile while at John's repast. Funerals can be sad, but they also can remind people of fond memories.
Maggie: Maybe he just lost sight of the horizon. I was watching this documentary on JFK Jr. You remember when his plane went down? ... Anyway, Kennedy was a novice pilot. He was flying at night, and the clouds came in, and his instruments were telling him which way was up, but he didn't trust them. The truth was right in front of him, and he couldn't see it. He lost sight of the horizon and nosedived, and by the time he realized what was happening, it was too late, and he couldn't pull up. Gary: What does this have to do-- Maggie: That's depression. Now maybe he wasn't depressed; maybe something else was going on. People keep secrets from loved ones, and sometimes, you don't even know they have these secrets until an event like this happens.
