Thank you for sharing, you are a lucky man. My grandfather too, lived to be 92. I loved him because he loved me. As a child, I'm sure he knew I was gay, certainly long before I even knew myself. But he loved me unconditionally, and because he was our patriarch, so did my relatives. He read the comics to me, he took me fishing with him, we went for long walks, we talked, we bonded. He protected me. I depended upon him, and he never let me down.
He, too, had a 60 plus year happy marriage. He told me the secret: The true relationship becomes the thing itself, to be cherished. Two become one. Gestalt. My partner and I are together over 40 years...and counting. Thanks, grandpop, for teaching me the true values of life!
