Depending on your sister and your relationship with your sister, you may need to defend yourself in different ways. If your sister does well with people who are straightforward, you should clarify with her what is going on with you using simple assertions. This means you tell her something or ask for something directly.  Start with the good, for example, “I appreciate it when you let me use your computer.” Be honest and straightforward about your problems. You can say, “But I think we have some problems that we should work on.” Tell her something that you need from her. For example, you can say, “I’d like you to knock before you come in my room.” You can explain to her how you feel, for example, say “Because I feel like I can’t trust you when you come in my room without asking.” This is especially good to do if your sister is someone who cares about being heard and/or is an emotional person.

This does not mean that you become aggressive with your sister. Being more firm just shows that you are serious about your boundaries.  Start nice, and say something like, “I’m happy to have you come in my...
