No, I think I just thought it sounded like a pretty name. Later I realized I had probably heard it once before in a Bruce Willis movie, where one of the main characters (who would save the world) was named "Lilu".
Thank you, I love chipmunks also. I was a little surprised also, but Lilu surprises me a lot. I must admit I was ready to turn and dive between them, if need arose, as I was not ready to witness tiny bloodshed. :)
