Stuck in the Middle

IFLS has published a video in a post with the title "How Does The Order In Which You're Born Affect Your Personality?"

The article includes the following line: "Those of us with siblings will have heard it all before - the oldest is the bossiest, the middle child is the most co-operative and laid back, and the youngest is spoilt."

Given that, I am sure that you will be shocked to learn that I was born in the middle. Yup, "most co-operative and laid back"... Describes me exactly. ;)

I thought the tradition was: the oldest one inherits the kingdom/business/etc., the middle one joins the priesthood (or, in modern times, academia), and then you lose count.

By the way, I don't actually care about the video; I just want to be snarky.

Update: After watching the video, let me encourage you not to actually watch it: it's painful. The whole point of my post was the IFLS blurb was good (or at least convenient) excuse for me to be snarky.
