Curate, connect, and discover
I'm aware we make fun of katniss for not realising everyone liked her and that peeta wasn't trying to play some strategy in the game, he's in love with you goddamnit, but
Katniss's entire existence up to that point since her father died was just. Survival. Not just for her but for the two family members she has left. It's been pointed out for ages that katniss, while being vague about so many details it's insane, will always tell the reader exactly what she ate and when and how much. She catalogues her days by when she retrieves food and when she sees her sister.
That's all she's had room for in her brain till then. Survival. No room for friends, romance, normal social behaviours longer than "geasey sae gets more than she should for that price because she's the only one who'll pay for wild dog".
Katniss my beloved traumatised girl, you should've had a breakdown sooner. Fuck the movies for leaving out her breakdown at the end. It was coming for a very long time.
