Thoughts.......on surgery

I still don't know what to think of my father's surgery tomorrow. I guess it's good for him, but is it the right way to do it? Will he follow the diet? Or be one of the few that it doesn't do anything for because he keeps eating the same way? What will happen in surgery? Will I end up wishing I spent more time with him? Or will I still not care? I guess I've never really let my feelings on this come to the surface before now. His choice is his choice......I just wish they would've thought of the kids and our economic status first.
