I am rather fed up with mine. And they are with me. None of us is nasty or tragic, but I suppose we don't get along well.
I realised the other day that it's just quite a tricky relationship and nobody can really relax and be themselves - I have been myself, and it hasn't gone down terribly well. EG I make a sarcastic joke and they think I'm being horrid - dh takes it as a joke but he knows me.
Loads of people on here moan about their in laws, so come on, what makes it better and what can you proactively do to make things easier (if not deeper)?
