<p>if you for some strange reason really dont want your roommate changing in the room, just get a webcam and mount it on top of your monitor (with the monitor in a corner where it has a view of everything). You dont have to actually hook it up, just spend some time looking at some random other webcams and say stuff like “hey look, my friend at UCLA has a webcam of his closet and dresser” do that and maybe some video chat with someone you know.</p>
<p>They will probobly get paranoid that the camera is watching and go somewhere else.</p>
