President Barack Obama has complained about the loss of privacy that comes with being leader of the United States, regretting the loss of simple pleasures such as a long walk or a trip to the car wash or supermarket.

"I just miss – I miss being unknown," he said. "I miss Saturday morning, rolling out of bed, not shaving, getting into my car with my girls, driving to the supermarket, squeezing the fruit, getting my car washed, taking walks. I can't take a walk."

His dream, he said, was to "go through Central Park and watch folks passing by ... spend the day watching people – I miss that".

Faced with criticism for playing more golf than most previous occupants of the White House, he explained that the sport was simply the best way of getting relaxed.

"It's the only excuse I have to get outside for four hours," he told Hearst magazines.

Though he said he enjoyed his life in the White House, he felt disillusioned（醒悟的，幻想破灭的） with the some of the ways of Washington, which he has failed to change, such as the "kabuki dance（日本歌舞）" among political parties before serious policy discussions begin. His comments may be seen as excuse by critics who have accused him of appearing too detached（漠然）, and being slow to engage in important issues such as Libya and the near shutdown of the US government last week.

Since arriving at the White House in January 2009, Mr Obama has already racked up（打）60 rounds of golf in office, more than George W Bush did in his eight years.

In terms of ability, Golf Digest magazine has ranked Mr Obama eighth out of the 18 presidents who played the game since it became established in the early 20th century.
