holiday frenzy from N in-laws - what to do?

[stranded]

I've developed a nose for the Ns, very, very slowly, but surely.

Now that I know about N's, I trust my gut when I meet someone.  It's eerie - the shock you get when meeting one once you know about this type of people.  It's instant revulsion.  My husband met a friend of a friend, and the second he met her, he said he could feel himself recoil in horror!
