I so glad to hear that Zac is making progress and happy to hear that his spirits are up. Although that doesn't surprise me after hearing your stories about him. He sounds like an exceptionally brave and mature little boy and he is (and you too, Unk) an inspiration to me. I think we can all learn a lesson from Zac and especially during the holiday season, it helps to point out what is really important in our lives. I wish him continued good luck with his treatments.
