I'm Worth One Phone Call. Right?

I would think so. I'd say I wouldn't expect this of him, but he's kind of an enigma to me, and it actually seems like something he would do. I'm not sure what I can tell you other than I think you should do what you think is best. If it makes you feel any better, which I doubt, I don't know of anyone who has heard from him. Not very many people knew he was actually gone. If you do wait for him, I'm sure he will do his best to make it up to you.
