My foot twisted just now as I was heading toward my desk, and went out from under me. And it hurt so badly I gasped out loud. At work. And cursed profusely under my breath. And gasped out loud again.
Fortunately, my boss was just taking the people in the waiting room into the conference room, so it covered the noise and I don't think anyone noticed. And my ankle seems (with help of the brace I always carry in my purse) to be taking my weight again. But that was Not Fun.
