I'm so very VERY sorry to hear this Ephraim :-( I went through the same thing with my father. I only have 2 words to say to you. NO REGRETS. If you love him, TELL HIM. If you've been proud of him, TELL HIM. Leave nothing unsaid that NEEDS to be said to make you BOTH proud of each other. Don't be afraid to talk to him. Cancer is AWFUL, hateful, as far as I'm concerned. I will keep you and your father in my prayers, please take care.
