Russian President Vladimir Putin looked like a schoolboy being shunned by his classmates at the G20 summit in Brisbane in November 2014. World leaders were visibly awkward while shaking his hand and talking to him; tense and restrained, Putin seemed almost like a pariah. Being photographed with the other BRICS leaders breathed some life into him, but his eyes only really radiated warmth when he was being hugged by a koala, the only creature that seemed to understand and forgive him.
