I never really knew my dad. He died when I was a toddler. But my dad gave me the greatest gift of all: life. He also gave my mom the confidence and courage (and the foresight of a modest life insurance policy) so she was able to survive as a single mom after his passing.
I thank my dad for those blessings, even though the time we had together on Planet Earth was much too short. They may seem minor compared to what many dads have given their children, but they mean everything to me.
