Wherever you go around Athens you'll see gaggles of some of the 45,000 uniformed volunteers who are helping out at the Olympics.
They're described in the publicity materials as the "motivating force and soul of the Games."
At the risk of sounding like a heartless hack, I beg to differ.
While well-intentioned and endlessly friendly, many of the volunteers boast more enthusiasm than ability.
Ask them when the next bus to the media village is and you often to receive a blank look or a shrug of the shoulders.
Ask them where the press conference rooms are and they often don't know.
Ask for a cup of coffee or a beer and you're often still standing there 20 minutes later.
Try to take a photograph, film a venue or set up a satphone, though, and you're likely to have one of them on your back, making your life a misery.
I try not to lose it. They're giving up their time for nothing just because they want to be part of the Games and they've probably had inadequate briefings beforehand. But on occasions I find my patience severely tested.
