Glad to see the HT is treating your dad well!
You know, when you consider that it's only been a short time since discovery, surgery and the realization that HT was needed - well, that's a lot to deal with. The expectation/hope is that the cancer will be gone once surgery is over and when that turns out not to be the case it's a huge emotional issue - not to mention the physical side of it. With the help of your mom and such a caring daughter your dad is on a good path. Your dear little boy is such an addition to his life - he's a fortunate man.
May 2008 be good to you & yours,
