Re: PAIN IN THE ****
^lol. i know how frustrated you are, trust me. been there done that but that's just how it is in Pakistan, you gotta let it go otherwise you will drive yourself crazy.
Before I left I sorted out mine and hubby's room how we wanted it, sorted out all his clothes; he knew where I had put everything plus I neatly had all my stuff in one cupboard for next time I go. I came back to the UK, hubby came a short time after when he got his spouse visa (just for a holiday as he's finishing his degree), when he went back he said his mum had decided to go though all our stuff and re-organised it how she thought fit, including putting lots of stuff away in suitcases so half his clothes has disappeared!
I know I'm probably gonna get blasted for saying this but a lot of that generation of women in Pak just don't have much going on in their lives, especially no control. So when they get a bit of something they can control they go to the extreme.
Just chill, accept that's how she is and you will be a lot happier. Don't let anything she does take you by surprise or make you angry.
EVEN if you are right too, men don't want to keep hearing about this stuff so if you don't want to make your hubby annoyed just don't mention it unless it's something worth mentioning.
