Hmmm....she sounds ENFP is most ways but she's got some of those leadership qualities of the ENFJ. I think she's a leader not because she's in any way strategic/objective or purposely trying to make others look good - it's more that she's just incredibly enthusiastic about what she's involved in and it rubs off. I'm going to brag () and say that she's got some kind of charisma that people are drawn to.
On a side-note - her social life is killing me. She's gone to 4 grad parties between yesterday and today, had a friend sleep over and is now she's at the movies. I think our home is just a hotel for her. I guess that's the life of an extravert. I wouldn't know.
