Genetics is a funny thing

When I was growing up, my sister Sara used to rub her nose with the corner of her baby blanket. She's always done it for as long as I can remember. After she had Chloe we were driving in the car one day and Chloe started rubbing her nose with her baby blanket. Sara and I were freaking out. Chris didn't believe us at first that she had spontaneously started doing it but she did. And now Jenna has started doing the same thing. You'll have to trust me when I say that I did not and have at no point shown her how to do this. It is not a mimicking behavior. Bottom line is this, I don't care how she got here, she belongs in this family.
