I just wanted to add my two cents:

I work as a nurses' assistant/caregiver for disabled people.

An LPN (who is overweight), another caregiver (who's normal), and I were at the park in Puget Sound pushing three of them in their wheelchairs.

Now keep in mind that I'm a size FOUR. I heard these women (not my co-workers) talking about me!

I had jeans that had a repair in the behind (I bought them second-hand) because I don't wear good clothes to work (I get all sorts of bodily fluids on me and there's no sense in ruining good clothes). They were discussing how natty my jeans looked and how my big butt probably ripped them open.

I figured these two females were teenagers, but when I turned around to let them know I had heard them, I was surprised to learn that these women were in their early forties !
They just giggled when I looked at them (I kept my mouth shut), seemed a tad embarrassed, and then proceeded to verbally destroy a co-worker of theirs.
And neither of these women were model-types, either.

It's amazing how intolerant some people are. Would they make fun of me if they knew how much weight I've lost??
