Dear Diary: Today I met with President Park Geun-hye, the first female president of South Korea. We had lunch with Joe Biden followed by a press conference. Korean is not one of the many languages in which I am fluent. I was glad to have Joe present to fill awkward silences. Bo wandered in looking for attention. "How do you like the dog?" Joe asked her. She wrinkled her nose with distaste as she chewed. "In that case just eat your vegetables," said Joe. I then treated her to my performance of Gangnam Style which Sasha and Malia had taught me. President Park covered her mouth and made a strange gurgling noise. She was clearly hugely impressed. But enough about me.
