I said hi. She'll be worked up that you considered it important enough to say goodbye to him, but not her. In my case, it's true because I don't, and am not stealing his girlfriend. I then take the feedback and use it to hone my skills. Also, for the record, I do not advocate hostile girlfriendstealing.
Violence is only funny if it happens to someone else.
You're trying to coax her out and take some food from your hand. Don't make any large, sudden movements, or something silly like run after her. The goal, the art, and the satisfaction is in getting her to come to you. As girlfriendstealers, this is the only important thing. Keeping her is up to you, but we don't care about that.
