I'm a bossy first born.  I think I had seven children so I'd be assured of always having someone to boss around.

I married a youngest.  And he's very, very much the "baby" of the family.  I probably was attracted to him because in many ways, he let me be the more dominant partner in our relationship.  Be careful what you wish for, though...sometimes, I can be a little resentful of feeling like I'm always the one who has to be "the boss".  Yeah, yeah,yeah, I know....
