That's actually a really often observed behaviour. The bronze winner is very happy, whereas the silver winner is not. It has actually been studied in psychology, and it's sort of because of downward comparison. The bronze winner is happy because he won a medal, but since he was still two away from getting gold, there's nothing much he could and he's happy. The silver winner feels that they were just so close to gold and barely missed it. As a result, they aren't as happy.
