When I was 14, I was asked what I would want as my epitaph. The best I could come up with, after a few minutes of serious thought, was "It seemed like a good idea at the time." Twenty years later, that's still the best I can explain about why I do anything.
I thought this was the most heartwarming story I've read this year. Go read The Magic of the Quilt at Jean's blog and be overwhelmed by sniffles and awwwwwws. Then go give something to your LOCAL HS. (Not the HSUS - there's a difference.)
