I don't like that her sour face is being seen as bad sportsmanship in that buzzfeed article. She seemed displeased with herself far more than she seemed angry or envious of her competitors. Wearing that disappointment so...blatantly doesn't surprise me. Hiding it well is a skill we humans tend to master later in life.
really funny pics, whether she was disappointed in herself or pissed that she received a silver she still should have got on that podium with the biggest smile on her face! a silver medal at the olympics is nothing to be sour about
