the funniest thing happened on the way to work today. i was leaving waterloo station and this old haggard homeless guy in a wheelchair was attempting to cut a swathe through the commuters, when all of a sudden this well-dressed, middle-aged woman drops a load of change in the coffee cup he was carrying. he looks at her, she is obviously waiting for some gratitude, and he blurts "you dropped it in my bloody coffee" - i swear the look of embarresment on the woman's face was more priceless than the contents of tate modern. laugh - i cried!
