Have you seen the movie "March of the Penguins" yet? If you haven't, and you are a parent, you need to see it. Any sacrifices you have made for your children will suddenly seem insignifigant. Goodness! Going four months without food in order to protect your offspring? Walking for a week to get to a food source? I don't even like going to the grocery store that's five minutes from my home. And I get to travel in a cozy car. I'm just pitiful.
After watching the movie Christmas Eve, I told Griff, "You are a great father, but those penguins have you completely beat." His response? "Right back at ya'!" (well, not exactly, but close enough)
