All generalisation rules apply:-
No initiative. Struggle to do simple tasks.
Self-centered, often egotistical.
Don't care about anything, only a few exceptions. Will go along with whatever, as long as harmony isn't breached (their values actually mean nothing when the cards are down).
Fickle and fake on the surface. To all strangers and, depending on their mood, to friends as well.
Terrible at expressing themselves, especially emotions, unless given a large amount of time to do so (even then they can't speak about their mystical "everyone else has them" feelings).
