Aspen Matis said this quote

I was passive by nature. I had always been. Arguing felt unnatural and uncomfortable. I was always agreeing even when I didn’t really, instinctively looking for ways to forfeit power, to become more dependent, to be taken care of. I realized how intensely Icecap reminded me of Jacob. They were similar, both diligent and harsh in their judgments—and my big brother’s sureness had always comforted me.But as I ran on sore legs to keep up with Icecap, my tendency toward silence stressed me.
