Ejecting the Cuckoo From the Nest

"On the train back home, I found a scathing post online. [My sister-in-law is pushing thirty but isn’t married yet. She comes home all the time. Would you be bothered by it?]The comments were numerous and ran the gamut of opinions. The post got wildly popular, and there was an argument between the poster and commenters. [It’s bad enough that she won’t get married. She wants to stay with us when she’s home. Shouldn’t she feel ashamed? I’m at the end of my rope. She even drank all my lemonade last time she was here. I really hate her.[She has no boundaries. I’ve been wanting to teach her a lesson for ages. I turned her bedroom into my walk-in closet. Let’s see if she can still stay here.]When I got to this point, I closed the post.It was lucky that I bought the house where my parents and brother live. Because of that, I would not be at risk of losing my own room. But when I got out of the train station, I received a text from my mother. [Sweetie, I booked you a hotel room. You don’t have to come home and stay this time.]"
