The Effects of Gravity

My bellybutton has become an emoticon.
You know, those little faces that people use in text messages and emails.
My bellybutton use to be simply a circle, sometimes deeper sometimes more shallow. Three different times it became a taut dot on the mound of my stomach swollen with baby.
Just this morning, as I stepped out of the shower, I noticed that it has taken on a distinctly different look.
It looks like this on the top: ^
And the bottom is like a parentheses turned on its side. A smile. So at least my bellybutton is a happy emoticon.
I imagine that the emoticon at the top right of the photo is the closest to my belly button image.
Now what does this have to do with gravity? Well, I actually tugged on either side of my belly button and pulled it upward. The ^ disappeared. Which means gravity has had its way with the skin on my stomach which I consdered fairly tight.
Something else for me to worry about, or I could just accept that my belly button is trying to express itself. It has gotten over the look of surprise 0_0 and moved on to happiness and acceptance.
