I have created twenty-six characters to date and so far have only one character I really dislike. This is Twoface. She looks straight at you and smiles. Superficially she looks like a pleasant enough person, very non-committal though. Her response to what you say is usually: “Ah, yes” or “Really” or “Indeed.” But you know exactly she doesn’t give a toss about anything. Even worse, when you turn her around, she has a second face rolling her eyes and it is very clear she believes everybody (except for herself) is a tosser.
I haven’t incorporated her in any stories yet, but I think she will become the boss. I will only use her if absolutely necessary.
Now that I look at her second face and know that she is the boss, I feel slightly sorry for her. She must be in middle management and feels a bit of pressure from higher up. While she rolls her eyes, she does look a bit scared. But still I thoroughly dislike her behavior and I will stay clear of her as much as possible.

I have seen that second face before. Mostly out of the corner of my eye.
She doesn’t like to do it publicly. But if you have seen it out of the corner of your eyes, I must ask you… you haven’t been rolling yours, have you? :)
