How can I stop my younger sister being mean to me and thinking she is better than me?
I am 20 and my 16 year old sister thinks that she is better than me. She is very confident and thinks that she is more mature than me and that she can do and understand everything better than me. Every time I come home from university I try to be nice to her and have a better realtionship with her but I just can’t because it’s very undermining to have a 16 year old treat you like a child when you’re 4 years older than her. She tells me what to do like she’s older than me and talks to me like I’m completely dumb. I’ve tried to talk to my parents but they won’t do anything about it. My mother likes that my sister is the way she is because she’s glad that she has a lot of confidence unlike my mother or myself. My father understands what I’m feeling but would never stand up to my mother or sister. How can I put her in her place and show her that she isn’t abover me and that I am the adult not her? I can’t be mean to her the way she is to me because I would feel bad for upseting her. She on the other hand knows that I am a sensitive person and will say anything she wants to upset me without feeling any guilt. How can I stand Up to her?
