Sister lets her sister use her room when she is not home, but now when she comes back, everything is a mess, clothes are everywhere, so she wants to make her stop: 'Yesterday I told her she needs to stop going into my room when I'm gone.'

Why would you act like this towards your sister? They're doing something FOR YOU.

I hate entitlement. I can't even explain it, but I hate it; I really do. Is awful how these people act as if they were able to do whatever they wanted just because they can. They don't care about other people's feelings or desires. They just care about what they want and getting it. An example to make them understand why everyone hates that kind of attitude is to say that it is like if they were a little thirsty and took away everyone's water just to get satisfied. Without considering if other people need the water as well, or even more than they did. They just took it because they could. If you say something like this to them, they will probably just dismiss you and treat you as if you were overreacting, just like this girl did. 

This sister saw an opportunity to take advantage of her sister and took it. It didn't matter if, by doing so, she was making her sister uncomfortable or crossing a boundary. She could do it, so she did it. That is the motto guiding this kind of entitled people through life. "I do it just because I can't, and I would never spend not even half a second thinking about other people or how they are affected by my actions and mistreatment". Is there a possible and functioning way to get them over that? Is it possible for them to feel bad about the awful things they do? Is it possible to get them to feel ashamed for acting like that? I don't know. But I for sure will be looking for a way. These people can't just go through life expecting everyone to be accepting of their awful character just because. They need to learn to feel sorry and ashamed for the way they behave. They are adults who need to be responsible for the way they act and treat people; if not, one day they will learn the hard way and really regret it. It starts with being disrespectful of somebody's bedroom; it ends in unstoppable craziness.

  • Am I wrong for refusing to let my sister use my bedroom

    My sister is staying with us for a few weeks while she looks for a new place. She has her own room but keeps asking to use my bedroom when I'm not home because she likes the bigger mirror and says my room gets better light. At first I didnt care but lately I've come home and found my clothes moved around, my drawers open and stuff on my desk being used without asking.

  • Yesterday I told her she needs to stop going into my room when I'm gone. She got really offended and said we're family and I'm acting like she stole something. My mom also thinks I'm being dramatic because she's only using the room for a few minutes at a time. I told them it has nothing to do with how long she's in there. It's my private space and I want to

  • cottonmercer666 NTA. I never understood siblings who use the excuse, "We're sisters!" When they want to invade someone's privacy. Its your room, and your property. You have every right to keep it secure and out of the hands of other people.
