Don't know if I'm being a bit over-sensitive but my husband's ex always insists on coming into the house uninvited when she comes to pick the kids up. They're 12 and 18, it's not like they can't make it down the garden path on their own. It drives me nuts as the boys will faff around getting their shoes on and stuff together etc, taking ages, all the while she's stood there. I don't really want her in the house - it's not even as if she makes an effort at smalltalk or whatever, it's all really awkward.
So the other weekend when she turned up I knew they weren't ready, so I opened the door and said 'hi, they'll be out in 2 minutes' and then closed the door on her, thinking she would go and wait in the car. She didn't...she just stood there with the door closed in her face.
When I pick my daughter up from her dad's I call her to say I'll be outside in 2 mins and she just comes out - surely that's what most normal people would do??
