Where Did I Put That Book?

I had some technical algorithm work to do at home, so I took my copy of "Numerical Recipes in C" home with me. When the time came to use it, I couldn't find it anywhere. It wasn't in the car, wasn't anywhere in the house that I could see, it wasn't at work (I thought that maybe I'd forgotten to bring it home). It seemed to have disappeared from the face of the earth.

I asked my wife about it:

Me: Have you seen a big, red reference book anywhere?

Her: No. What's the name of it?

Me: Numerical Recipes in C.

Her: Have you looked in the cupboard where we keep the cookbooks?

Sure enough, there it was. It turns out that the student who watches our kids after school had been tidying up and "recipes" was the only word she recognized in the title so she put it with the cookbooks.

What impressed me most, though, was the fact that my wife immediately knew where it was when I told her the title.
