how do you react when other people keep on comparing you to your sister?

I've been there. And I wasted some time feeling inferior. But what's funny is now that we are both "grown up", people actually tend to like me better. That doesn't mean anything to me, because I got over long ago worrying about being compared to my sister. She is talented and smart, but hey, so am I! It just took me a while to figure that out. YOU are special in your own right!
