Okay, I know you're all thinking "Well, duh but today I've come to a realization.
When I was a little girl, my mom would constantly remind me to "sit like a lady," that is, sitting with my legs together instead of having them splayed out, which I still have a habit of doing. Even now, at 23, my mother still tells me to "sit like a lady" when I forget I'm wearing a dress or skirt and accidentally show off my "underwear area."
Well, today I was in the waiting room at the doctor and I had the misfortune of having a fat sit across from me. This fat, of course, had a FUPA which made it impossible for her to put her legs together. This is something I've noticed with all fats. A teacher I had when I was a child was so fat her stomach was essentially between her legs when she sat, and her legs were practically spread about two or three feet apart. I used to think that's what it meant to be bow-legged. So, because fats can't put their legs together, there's no way they can be "ladylike" (at least in my mother's opinion) when their fat prevents them from sitting like one.
