@Willow a long, long time ago I had a tragic set of incidents that nearly killed me. It helped me realize that I wanted to live (a nice change of pace) but I didn't know what to live for. My high school girlfriend put a book in my hands where the main character learns that the point of being alive is to love and be loved by others.
Ever since then, every time I've had a chance to name someone in my life, it's been a name from the book.
Naturally, I did the same for myself. And that's how my wonderful 17 year old cat and I are named after twin sisters.
