Copy cat 'Sibling' Please. Please help me. D:?

I think that you should tell her this, exactly what you just said. Have you told her parents about it? If she's not comfortable with who she really is then thats a problem. Or maybe she secretly looks up to you? lol, hell, you never know .. Sometimes i still try to do the things my mom does, lol. Because i love her :) But yea, just let her know that there is nothing wrong with being yourself. Tell her you want to see HER personality and things that SHE likes to do, and not what you like to do. hope i helped? :)
