I'm 8 years older than my sister. I remember that everything that she did, said and thought used to bother me, I was a pretty cranky teenager. I did argue with her a lot. I moved out young and I didn't expend time with her during her adolescence, we reunited as an adults and we share a lot of things! I can say that she is my best friend now. I always wonder how would have been our relationship if we had lived together during my tweenies and her adolescence.
