SIL and BIL are coming to visit MIL today, and because it's too much effort for them to drive the 30 minutes more than twice a year (or host any of us at theirs), we are expected to be there too. MIL is lovely and has had some serious health issues lately, BIL is a bit soft but very nice, and their kids (in their 20s) are also lovely. The issue is SIL. I am absolutely dreading seeing her.
She's rude, selfish, ignorant and I just cannot get on with her, although I have always tried to be polite because that's the right thing to do. But even her kids and her husband apologise for her behaviour. The biggest problem is that she will spend the whole visit banging on about when are we having more kids (DS is nearly 3). We don't know if we want any more or if we can have any more, but she will not shut up no matter whether she is asked to or not, and if we walk away she follows us.
So, wise MNers, how can I tell her to fuck off leave the subject alone without being overtly rude??
