I think she must have been swapped at birth with someone else's child.

Barb and I wouldn't have a child that received her lowest grade in math! We meet each other in algebra class and each took four years of math in high school followed by I can't remember how many math classes in college.

<heavy sigh>

I suppose we have to keep her now.

Update: This just in--a picture of Xenia and I are in this article about an Ohio dad jailed after daughter fails to get GED. We are the picture on the far right of the row of pictures.
