Aw...sibling feelings. Love this:

I ask questions and she considers, pursing her lips. Her opinions are as strong as her eyes. When she turns them on me, I am unnerved and irritated in the way of siblings when they disagree. And I often disagree.
Once I was her champion.

Maybe I'm projecting (are you the older sib?), but this really made me reflect on my own relationship with my younger brother. In a lot of ways, we are incomprehensible to each other, after fighting in grief and then living apart for a while. I like us better now that we're adults, though, even when I don't understand him.

Great work!
