Let your sister know what the problem is, using “I statements. ” For example, “I feel belittled when you talk to me like a little kid” or “I feel angry when you choose not to respect my clothing. ” Avoid the word “but. ” This negates everything you’ve said before. For example, instead of saying “I see where you are coming from but I think you’re wrong” try “We can’t seem to agree on this. ”

For example, you could offer to knock every time you want to enter her room and she could offer to say “Hi” to you at school.

Instead of manipulating you into doing something, you would like her to ask you for help or a favor. For example, when she starts to yell at you, will you walk away from the conversation? Or, if she bullies you, will you tell your parents?

For example, you could say, “Linda, I want to establish some boundaries with you. I will not tolerate you bullying me any more. When this happens, I will let mom and dad or another adult know right away. "

For example, you could say, “Linda, do you have any boundaries for our relationship?”
