I'm just guessing but I'm willing to bet that your favorite adults in the whole world have a 'child like' quality about them. They've never lost their enthusiasm for the world, or wonder, or their wide eyed thirst for the unknown. The last few days with my Grandson have been a pleasure. His excitement for life, and Christmas, and Santa, and the gifts he plans to give, and get, are so very heartwarming. It makes you want to protect these young people so that they never find out everything about life.
I asked him if he knew what tomorrow is, and with great anticipation in his voice he said, "Tomorrow is Christmas Eve when Santa comes and then we get up on Christmas day and celebrate the Birthday of our King."
If that doesn't get you excited, then you're officially old.
As for me, I'm good either way, I have a pot belly stove with a 'coal burning' grate in the bottom.
