As I was going to Olympia...

I sat on the District Line train on its way to Olympia. Four middle-aged men were on their way to the BETT exhibition (its about IT in education). Boffin types: middle-aged, beardy, large lips, rimless glasses, brown shoes. Something about certain institutions but staff may grow to look alike over time, or maybe they are hired that way. They sat in a formation where 3 were on one side of the carriage and one was opposite. As the train trundled along the one on his own read out an advert to the others, "have you found the right treatment for your erection problems?" They had a discussion in dutch - lengthy. "Man Matters" he said at the end - presumably they were asking who the advertisers were.
