What's wrong with those purchases Suzy, I'm not even manic and I have a picture of the encyclopedia salesman trying to sell me (he was cute :-)
What was I watching the other night? "Bridget Jones Diary" I guess, and someone made some comment like, "Just because you're depressed doesn't mean you can't have a sense of humor."
When I get really low I do start thinking of Jimmy Stewart and "It's a Wonderful Life" and that maybe there is a good purpose for me somewhere, even as a good example of something.
