My best friend and I have been good friends since elementary school. We graduated high school as co-valedictorians, stood up at each other's weddings, compared notes through medical training (me as a nurse, her as a doctor), and generally did everything together. Through all this, I was the calm one. She was the one on Ritalin. She would want to run around in circles and I would be the one holding the video camera. She would study by talking and obsessively cramming between study breaks; I would read my books in my room and the quiz myself in my head.
Somehow, by the grace of God, we also became moms at basically the same time, and we both had girls! So, whenever we can, we get the girls together. I knew something was funny when I visited her for a week after her daughter was born, and little baby B actually slept for more than 45 minutes at a time, and "cried" by saying "meh" (and only when she was hungry). The irony became much more obvious the last time they saw each other. I could describe it, but you can see it best in picture form... guess who got the calm child and who got the hyperactive one?
