This happened to me twice today.... Firstly when a delivery I'd forgotten about arrived, when I was still in my dressing gown feeding the baby, then just as DH got home and I was about to put dinner on, SIL landed at the door with her children, who are currently going through a "challenging" phase. She likes to sit and have a calming cuppa while they "challenge" us. They've just left and the house is a mess.
So who brings out the "oh no" reaction in you when you hear the door?
