We are having a couple to stay with us in september. I don't know the woman very well. She is by all accounts a good egg, and I know she had many fine points. She is also boastful about her (grown up) children and neices and nephews, and is also quite opinionated generally. Without going into detail, I don't agree with some of her opinions. I have seen enough of her behavour in action to feel apprehensive. I know if I mention any minor achievement of my sons, dh or I, she will have top it.
Any tips on how I can stay on friendly terms with her over a four-day stay? Me leaving her alone to do her own thing is not an option.
