Seriously, you must have deadbolt exterior doors now, and use them relgiously it sounds like Carsten. A friend had her little girl go outside, and wind up at a neighbors house while she was taking a nap. That\'s a tough situation, she works nights, keeps kids days while husband works. Frankly, I do n\'t see how she ever gets enough rest, but anyway, it underscores what happened this morning with the bathroom door! You have got to pay more attention now, she knows the combination. She\'s solving complex equations now!
