My FIL and I get on quite well, have very little in common but can pass the time chatting about DS's. He always calls in unannounced with some random guest or friend in tow and I seldom know the person. He calls with no notice and always seems to catch us mid breakfast, before me or the DC are dressed and the house is still in disarray. He expects me to drop all to make coffee and talk nonsense with this stray(for the want of a better word), all the while commenting that the house looks a bit disheveled and asks if my children own clothes! This infuriates me but also is embarrassing because of the random uninvited guest. So AIBU to think that his behaviour is completely unacceptable and unfair to me and my family. DH has asked him to at least give some notice before he lands in but it seems to fall on deaf ears
