My two daughters. My eldest is almost 14 and my youngest is 9. I never really understood anything about sibling rivalry until they came along.

Needless to say, no matter how bad their arguments get? If one is hurt or being bullied, the other steps up to bat. (almost literally

). Their relationship has taught me a lot about myself and a lot about how they love each other unconditionally, and how to add new words to the English language almost daily without effort.
