This really knocked my socks off. You are an exceptional young writer. You grabbed the theme and ran with it.

One small confusion....you said, "She hadn't been sleeping well lately," but you don't identify WHO "she" is. We would assume it is the mother, but later we figure out it is his sister and he is sharing her bed. But then how can the boy "see" what his mother is doing in the next room. You say she sinks to the floor. How would he know that if he is in the other room? Just a few tiny questions that maybe you could have fixed. Still, a powerful story.

A dramatic and emotional tale. A painful punch to the gut in less than a thousand words. I can see why you're a tough competitor in contests.

Excellent, nicely done.
