This dude just saved enough money to rent his first 1-bedroom apartment. The last thing he wanted now was for his older sister to move in with him.

Unfortunately for this author, that is the predicament in which he has found himself. At 21, he was looking forward to the experience of having his own space and finally getting to live on his own terms. He also had earned it. He saved the money from working jobs while being a college student in order to afford his own place. Sure, he is only 21, and most people his age are used to crashing on one another's couches and sharing small apartments because they cannot afford the luxury of personal space. Still, this guy was already tired of that life, and he worked his way to be able to hopefully never have to do it again.

This all happened before his older sister, who is 28, broke up with her boyfriend. She had moved back in with their parents and was not handling this transition well at all. She asked her younger brother if she could move into his place for an indefinite amount of time. The author probably would have said yes if it had been a night or two or maybe even a week. However, the fact that she demanded that he agree to letting her take over his new space without any specification as to how long it would take for her to get back on her feet was a red flag. 

After all, the sister is seven years older than the author and should be able to, at the very least, understand and respect the author's boundaries. Instead, she couldn't see his perspective. In fact, she even went so far as to suggest that she stay in his place solo while he went back to live with her parents. Her justification was that she was the person who needed her own space at this time. That may be true, but if she wants to live alone, she is going to have to pay for that arrangement herself.

  • We understand that older siblings often feel entitled to certain luxuries, but just because they feel that way does not make it true. The author's sister is old enough to know better. This isn't high school anymore, honey! 

    If the sister were polite enough to ask for a short-term favor and if she was willing to give something in return, maybe we could understand a world in which the author would agree to let her stay with him. Even if he did, that would be a level of generosity that he did not necessarily have to demonstrate. One has to wonder if this very sense of entitlement has something to do with the downfall of her former relationship. I'm not pointing any fingers, but it certainly seems like she's part of the problem here.

  • "[Am I wrong] for not letting my sister move into my apartment after her breakup?

    I'm 21M and I recently moved into a small one-bedroom apartment. I worked and saved for it while studying and just moved in not long ago. It's not big or fancy, but it's my first place on my own.

  • I still don't feel comfortable with it. I worked hard specifically so I could finally have my own space, and I don't really want to give that up right after moving in.

  • Now things feel awkward and I'm being made to feel like I'm choosing an apartment over my sister when she's already having a hard time. AITA for saying no?
