I was travelling on the London Underground during the Paralympic Games on my way to the London Coca-Cola Pin Trading centre in Hyde Park.

The tube was very crowded and I spotted three US Paralympians in their country tracksuits further down the carriage. I searched in my bag and found a 2012 USA flag logo pin and nudged the guy next to me, who in turn nudged his neighbour, who then brought the athletes attention to me.

Once I had their attention I held up the pin and gestured "do you want to trade?" passing them the pin. They gave the thumbs up and passed back a beautiful USA Team Hartford Foundation pin. They asked across the crowd where was I getting off? And they too were alighting at Green Park station.

We then traded 3 pins on the platform of Green Park. Very special pins to me that are to keep and not to trade.
