“ those glasses aren't for the sun they're for darkness, exclaims Rue. Sometimes when we harvest through the night, they'll pass out a few pairs to those of us highest in the trees. Where the torchlight doesn't reach. One time, this boy Martin, he tried to keep his pair. Hid it in his pants. They killed him on the spot. They killed a boy for taking these/ I say Yes. and everyone knew he was no danger. Martin wasn't right in the head. I mean he still acted like a three year old. He just wanted the glasses to play with, says Rue. Hearing this makes me feel like District 12 is some sort of safe haven. Of course, people keel over from starvation all the time, but I can't imagine the peacekeepers murdering a simpleminded child. There's a little girl, one of greasy sae's gradkids, who wanders around the Hob. She's not quite right but she's treated as a sort of pet. People toss her scraps and things. ”
