The lawnmower one isn't funny. That happened to a good friend of mine when she was a little girl, and she's lived with prosthetic legs since then. So don't laugh at that, please because she is such a happy energetic girl that it would break my heart.
I cannot verbally express how this really hits. Too often people treat fat as tho it is synonymous with ugly when it is not. I know I'm beautiful I'm also smart creative talented and FAT it's not a bad word it's a descriptive word.
