Meredith Grey (voiceover): Gratitude, appreciation, giving thanks. No matter what words you use, they all mean the same thing. Happy. We're supposed to be happy. Grateful for friends, family. Happy just to be alive. Whether we like it or not. Maybe we're not supposed to be happy. Maybe graitutde has nothing to do with joy. Maybe being grateful means recognizing what you have for what it is. Appreciating small victories. Admiring the struggle it takes simpy to be human. Maybe we're thankful for the familiar things we know. And maybe we're thankful for the things we'll never know. At the end of the day, the fact that we have the courage to still be standing is reason enough to celebrate.
