Ever since my children were born, I've had this observation that I've become more and more convinced of: my "Bellybutton Theory." That bellybuttons reveal or match the personality of the body they reside in.
For example, I am a straightforward person but an introvert at heart. Though I come across as outgoing and don't display the typical behaviors of someone shy, I am. I enjoy having a few really close friends that I develop deep relationships with. My bellybutton is fairly straightforward and simple, a basic cavern that goes really deep. It takes a flashlight to see all the way to the end of it.
My outgoing spouse's bellybutton has a few layers but is very close to the surface. And my children's coincide with the intricacies of their personalities as well. A combo of ours. Not one outie, though. But my very outgoing friend has an outie button too.
Interesting n'est-ce pas? What about you? Does your bellybutton confirm your personality?
