When I watched the first Hunger games movie with my family, and I saw Haymitch for the first time. I was like "Ew who is this bitch!? Omg Katniss and Peeta aren't surviving if he's their mentor". And I was disgusted when Haymitch first called Katniss sweetheart because I thought he meant it in a gross way, him being an adult and her being a teenager and all.
Now, I see a man who was stripped of his childhood, a boy who lost his mother and brother in a house fire, a boy who lost his girlfriend to gumdrops HE gave her out of love, a boy who lost his sweetheart, a boy who lost all of his little district 6 ducklings, a boy who lost all his friends to the games, a boy who had nothing left to lose, so he went to drinking alcohol to blind the pain. But when Katniss and Peeta truly need him, he stops drinking and CARES FOR THEM, he LOVES them as if their his children. Because if it weren't for Haymitch, maybe, just maybe, Katniss and Peeta would have become another Haymitch.
