If your wife had to live with her in laws (your parents) for 6 years...what do you think she would do? would she talk to you about it? Would she sometimes utter how everyone else is on their own and she had to live with in - laws with constant awakardness and respect? If you think the answer is YES, then you should as well talk to your wife about it.

You have not said, what caused in laws to live with you for 6 years. Is your spouse their only child? Do they have financial crisis at home? Were they persecuted back home thus can't  live back there? Do they have medical condition that they cannot live on their own???

I have seen great son in laws who are taking care of their in laws because the parents are in dire need of assistance and i have also seen in laws who just don;t give a fk about Jwain and when they come to your house, they think they are coming to their daughters house, ofcourse, the daughter is the bully in the house as well. Those in laws are shameless and " jabarjasti" kinds who have no repect for the Jwain.

Bottom line, if my in laws want to live with me for 6 years, they better have a good damn reason to do so.
