President Park Geun-hye shakes hands with Bill Gates, co-chair of the Bill & Melinda Gates Foundation and chairman of nuclear energy startup TerraPower, at the presidential office of Cheong Wa Dae on Monday. Bill Gates putting one of his hand in his pocket while shaking hands with the president gave rise to a question whether he was rude to do so. The presidential office said, Bill Gates took a similar pose for a picture when he met former President Lee Myung-bak five years ago. Just think of it as an American style of greeting.
