I was seeing it as passive aggressive because you were passively trying to get her to finish leaving the house. You forced the action upon her, but in a passice manner. If she wanted her stuff, she would have gotten her stuff, you didn't help her with anything. (Reading that it wounds harsh, please, read the words not the tone!)

If you dont' know what your goals are it might be a good time to go back to the beginning! I could use a dose of that, myself!
