A childhood belief about belly buttons

My bellybutton is an innie, but my cousin had an outie, which totally fascinated me, as it was the only one I had ever seen like that. She is Japanese, and I assumed that all Asian people had outies, a fact that I became very jealous about since it seemed more interesting than my innie. Whenever I was around someone Asian, I would ask to see their bellybutton. After I was told that was a rude thing to ask, I would just try to get a sneaky look at it. I was shocked when I first saw a non-Asian person with an outie!
