I haven't had much to do with mine other than what was necessary so she hasn't just showed up at all. I would be severely pissed if she did and I wouldn't let her in, I would tell her to go away and ring me to make a suitable appointment. We don't do unannounced visitors at all in this house, if we don't know they are coming they don't get in. Jack can't handle people in the house at the best of times but he needs warning so we can prepare some coping strategies for him
