This photo cracks me up!

My kids (probably like most) fight all the time.  The pick at each other constantly.  I know that's it's normal, but I was an only child so it's hard for me to understand why they just can't be nice to each other.  The do have some sweet moments as well.  My sister in law took this photo 3 years ago.  She doesn't even remember what they were laughing at, but I just love it.  It always makes me smile!
