I got a new running skirt last week.
"Mom! That's a really cute new running skirt! You look really good. Except (in a matter of fact voice) your chubby legs".
And yes, I was very amused, and not at all insulted. I mention her (and her brother's grasshopper legs) all the time. I DO have chubby legs (sorry about those genes, Daughter #2). Although, I'm not sure where she learned the word "chubby". I'm thrilled to say I didn't think it was a word she had ever heard.
Today after my run: "mom, did you have fun running? Are your legs thinner?"
Yes, dear. Yes, they are.
