Dear Prudence,
I share a one-bedroom apartment with my sister. I sleep in the living room. It worked out until she started dating “Nina.” Nina is over at our place at all hours of the day and night and has zero respect for anyone. I work the morning shift and need my beauty sleep. Nina thinks nothing of turning on the TV after I have gone to bed to watch a movie or turning on the kitchen lights and banging around to make herself a midnight snack. I am a light sleeper while my sister sleeps like the dead. Nina and I have had it out several times over her behavior to the point of our neighbors making noise complaints to our landlord. I told my sister that we either had to switch rooms or Nina couldn’t come over anymore. My sister told me I was being unfair and that my early shifts would wake her up as I would need to eat and make coffee before I left. I told her tough luck. Her sex life is not more important than my sleep schedule. We keep fighting about it. I can’t afford a place on my own and we have six months left on the lease. I might engage in some sorocide before then. Help!
