Every night, just before bed, heâd thank his bride of 70 years for giving him another wonderful day on Earth. That was the sweet-hearted nature of Jack Krieger, my familyâs next-door neighbor for more than 30 years. I first met him as a very young boy, shortly after my growing family moved to our brand new suburban house in 1964. As I grew up, I knew him as the dad of five children, a good neighbor and an usher at our church. Jack and his wife, Mary, would become lifelong friends with my parents, but I didnât know the full story of his life until last week.
