It's like I had a brainstorm while waiting at starbucks. Okay, what order are you in birth in your family? Oldest, youngest, only child, middle. Since I'm not pollish, this will not be a poll.
I think that tells a lot about them. I have my guesses -
CP - only
Mz - definitely oldest
Wef - middle
Spark - definitley middle
Let's hear it guys!
