My children. I know I've already done family, but I want to call them out. No matter how bad of a day I'm having, even if they are part of the reason (whininess, not listening, etc), they always do something that makes it better. Whether it be coming up and giving me a great big hug, telling me they love me, or singing along to Bon Jovi with me in the car, they manage to make me feel better without even knowing I needed it. I love that.
