I have been living with my parents-in-law for about 3 weeks, coming to 4. But my situation is different from yours because right now they are in good health and I much welcome the extra pairs of hands to help take care of two very energy-sapping children. My wife doesn’t have to bear so much weight in regard to cooking and laundry - and as long-suffering husbands everywhere know, when the wife’s mood improves, the general climate of the entire household is uplifted haha.

Which is why I forwarded you some happy sats from my recent food post haha.

I suggest that you write down all the things about them that annoy the hell out of you. I suspect that when you actually put it down on black and white, you will come to regard them as minor irritants (rather than major fault-causing lines). They will also occupy less power in your mind.
