Couple overstays in brother's apartment, demands privacy

When family members fall on hard times, it's natural to want to help them out. But what happens when they overstay their welcome and demand privacy in your own home? That's the situation one Redditor finds themselves in. The brother and his wife have been living with the poster for several months now, and tensions are high. The brother wants more space and privacy, but the poster is feeling like an intruder in their own living room. The situation reaches a boiling point when the sister-in-law creates a timetable dictating when the poster is allowed to use their own living room. The poster tries to talk it out, but the situation only gets worse, and the brother even goes so far as to install a lock on the living room door. Is the poster in the wrong for not giving their brother and his wife more privacy, or are they being taken advantage of?
