Hands down, they're my favorite. I can remember being frustrated at a friend and when he responded with a smile, I just couldn't hold mine back either. Suddenly I couldn't be frustrated and smiling at the same time. It's silly, I know...but its the secret to winning my heart (sometimes).
I can think of a few dear friends who may need to hear this song right now...just know, I will personally sit across from you and smile until you do too :)
oh and I love you.
