Have been told by a friend that my SIL told her that I never clean my and DH's house. It's so absurd. I said to my friend, you've seen my house - how does SIL think it is like that if I 'never clean'?! Friend shrugged and said 'I know, right?!' She couldn't offer any further explanation as to why SIL would say something so ridiculous.
For context, SIL is DH's sister.
