President Obama was injured while playing a “friendly” game of basketball at the White House. An elbow to the face resulted in 12 stitches (缝合) to the president’s lower lip (嘴唇). The man who elbowed the president, Rey Decerega, was unapologetic (不道歉的) and noted that Mr Obama is “tough” while playing basketball. Everyone said being president would be a hard job, but nobody knew that blood would have to be shed (流).
