so the past few days my wifes parents have been staying at my house. everything was going ok until today i randomly found him in my study.
I asked him what was he doing and he said 'now im sure you can respect the fact we all need some space every now and then to unwind' and closed the door...
I went to my wife and said i need to do some work that will take me a few hours and if i cant get it down i will be severely set back at work tomorrow so can she please as him to move to another room. she just said 'i dont have time to deal with this' and left with her mother for the afternoon
its been hours and he still hasnt come out, i even went outside and walked past the window and im almost positive i saw him going through my desk drawers
how can i approach this without it turning into WW3? at this point the only thing that comes to mind is jumping on the hood of his rental car to make the alarm go off and forcing him to get outside to stop it
