Hi, everything has a metaphor: even ex-husbands! Good luck with the exercises.

Speaking of metaphors: I've just spent an hour in a geometry nightmare. I've been "researching" geometry on the web, as geometry is (I think) the overriding metaphor for an essay I'm working on. It's kind of about a love triangle from high school. If I remember right, I think I got a "D" in geometry. But I always got an "A" in love triangles, alas. Yes, a real nightmare! Sue
