She was sent to us via aliens; hence the drool and the big eyes.
Come to think of it, that drool may actually be inherited. I do recall a time when my brother at the age of ten liked to tackle me, pin me down and let his spit dangle over my face while I screamed for the God's or Dad to come save me.
Oh, you finally get why I need therapy now huh? The spit coupled with the fact that my parents continue to ask why I haven't spawned one of these yet? I keep telling them that I would like to, but I haven't met any alien's that I thought were hot.
