My ILs are mild compared to some of you guys.
FIL insists on sending us warning emails of current scams going on by phone or email, totally weird things always perpetrated by someone on a country I have never heard of who are apparently targeting people just like me!! Like I have a special demographic called thick as shit.
Food at their house is always Luke warm and sliced or chopped very small/thinly, it's like they are preparing themselves for the retirement home. And there is never enough, DH could easily finish off what they cook for all of us put together.
FIL makes soup with leftovers (of which there are few) and will think nothing of scraping what you didn't eat into an old ice team carton to mush up into soup once they get enough detritus to do so. Chicken bone and half eaten roast potato soup anyone. They even freeze leftover Chinese takeaway!
He also uses one tea bag for about 4 cups of tea and you can't fox him by having coffee as that always comes in a shade of very pale gnats wee, I think it's a granule a cup!
And they don't have big glasses so you have to make yourself about 6 drinks to the equivalent of one you would have at home or try and quench your thirst with the lukewarm water/tea concoction.
Oh and you don't eat certain things together, god the issue when I even thought of serving carrots and fish at the same meal!
I do love them dearly though and think they just don't like waste. Mind you the hovering when you are doing anything, knowing in their mind they are horrified you are doing it that way but are far too middle class to comment gets to me and the time when a tap had been dripping and he taped a ruler to the side of dh's old baby bath to show me just how much water was being wasted did do my head in.
I am already storing up barminess from this thread to use to persecute DCs when I am old.
