My sister said it so well yesterday on Facebook, "Our sweet daddy left us today."
It seems like when people are stressed, tired, sick, or in pain their truest selves emerge more forcefully. In my dad's last days, it was his sweetness that shone most brightly. Even when he couldn't really talk anymore, he'd pucker up for kisses.
My dad was many things, but mysterious was not one of them. If he didn't like you, you knew it. But if he loved you, you knew that too. And oh, how he loved us.
