Very perceptive. Very sensitive/thin-skinned (more so than I, possibly). Very stubborn. Feels the need to tone down in public due to disapproval. Capable of handling household finances.

Wants things to go right. Giving/sacrificing. Persistent. Sometimes assertive. Wants to be there on time or early (I think). Less likely to follow the crowd. Seems to stress rather easily. Room is a mess. Likes to be with friends but dislikes being around strangers.
