That's funny she got in trouble for the pink hair! Serves her right!

I can imagine it's annoying when she says it's "amazing" that you're so much alike. It sounds like she wants you to be twins in every way, but then you want your own identity. Conflicting interests.

I suppose you could ask her if that's what she wants -- for you to be twins. You obviously don't want to be her twin for the rest of your life (and I can't blame you... I'd want my own identity too)... but it sounds like she does, even if she won't outright admit to it.

Personally, I would just be blunt about it. I would tell my sister that twins don't have to be alike in every way.
