👺Forecastin' tornadoes, brainstormin' retaliation

I caught my 24-year-old nephew in bed with his girlfriend in my house, and when I confronted him, his response made me regret allowing him to stay with me. Me: What exactly is going on here? Is this what you do when I'm not home? Nephew: Auntie, please don't start. We're both adults. Me: Adults? In whose house? I allowed you to stay here so you could go to work while saving money for your own place. I never said you could start bringing your girlfriend here. Nephew: So because I'm staying with you temporarily, I can't have a girlfriend? Me: Did I say you couldn't have a girlfriend? I'm asking why you think it's acceptable to bring her into my bedroom and lie on my bed with her. Nephew: It's not your bedroom. It's the room you gave me to stay in. I stared at him. Me: Excuse me? Who pays the bills in this house? Who buys the food you eat? Have I ever asked you for rent since you moved in? Nephew: And I'm grateful for that. But you can't use everything you're doing for me to control every aspect of my life. Me: Is that what you call correcting you in my own house? Nephew: Auntie, I'm 24, not 14. If you don't want me bringing my girlfriend here, just say so. But don't make me feel like I'm doing something wrong simply because I'm in your house. I was so angry I could barely respond. This is the same boy I agreed to accommodate because I wanted him to have a comfortable place to return to after work while he saved enough money to rent an apartment. I never charged him rent. I never gave him a deadline to move out. I thought I was helping him get on his feet. But now, he was standing in front of me, making it sound as though my generosity had somehow taken away his right to set boundaries. I told him that if he was old enough to make his own decisions without answering to me, then he was also old enough to find his own place. He looked at me and said something I haven't been able to forget.
