I have been watching the Clintons since they oiled their way out of Arkansas and entered the WH. I have always been fascinated by the fact that they will lie, even when they don't need to. It is as if lying is their go-to position for everything that happens to them.
There is no reason for her to lie about how she broke her toe. But, she does it anyway. Why? Both Clintons seem programmed to lie about everything.
Since she is lying and we do not know what actually happened, we cannot say that there was 'no reason to lie'.
Your comments are indeed valid, but I am more suspicious. Obviously my scenario was intended to be a joke, but the underlying premise was: She is hiding something.
