Feeling a bit lost

"Fred" is off enjoying his life. He's traveling the world, having people fly in to visit him, doing all the things he couldn't do when he was so sick. He hasn't answered any emails from us in several weeks. On one hand, we are thrilled that he is doing so much and enjoying his life again. On the other hand, I feel somehow lost without contact from him. There is just an empty sensation, like I've lost a good friend, yet the events that are taking place are exactly as they should be. Quite a paradox, eh?
