I remember seeing her before the Games. Before everything- before her dad died. She was so happy, and carefree. She was always smiling, or singing, or just being happy. I can't stand seeing her now- because of the contrast between the sweet, happy little girl, and the depressed, lonely young woman.
Now she's different. Prim was the only light left in her life. Now Prim's gone and Katniss has been left alone in the dark. Peeta can't be near her because of the hijacking, Effie wanted to stay in the Capitol, and I'm just an old drunk.
I can't stand seeing her now because she reminds me of me, just after my own Games. She looks so hopeless, and dead. It's like it just hit her that she's killed people. She needs time to grieve. Not just grieve her sister, and Finnick and those people, but to grieve for a normal life.
She needs to grieve for her childhood and her father, because God knows she was so busy trying to hold her broken family together that she didn't have a chance to have fun being a kid.
She will always have the scars, and the memories. Once you've won the Games, by the Capitol's standard, the real Games begin. And those Games are so much worse because the only escape is death. No way out, no chance of winning- just death.
Getting into a drunken stupor doesn't help, and neither does sleep, because it all comes back to life in your dreams. You see the arena in the ordinary things around you: the trees, the sky, the flowers. Everything, can take you back there, because there's no way out. No pure dumb luck or cheat sheet to help you out now.
