Well, you couldn't really call my brothers and my sister younger siblings, but they act like they are. I'm a quadruplet, but the oldest (by 3, 2, and 1 minute(s)), and I'm more or less the boss. It gives me an excuse when I tell them to do something, because when they ask, "Why should I do that?", I reply, "Cause I'm the oldest ". It works too.
