Mine was a funny little mistake. I was trying to come up with an email name and my husband said "OH, I KNOW!! How about Wendy Hoo...You know, from 'How the Grinch Stole Christmas." Wherein I had to let him in on the fact that it was not Wendy Hoo but Cindy Lou Hoo. Anyway, it stuck and the 9 comes from the 19th which is my birthday.
