A young woman's slight misfortune on the Piccadilly line from Covent Garden station was  good luck for me
Why?
Picture this..........
at the last couple of steps towards the platform, the noise that the train doors were closing was heard
I and some other commuters decided to try our luck to board; some got on, some didn't 
I was one of the latter........no wait a minute!
The young woman in front of me had managed to get her bag jammed between the now closed door
Try as they could others trying to help the door wouldn't open
Then........
All doors opened and I jumped into the slightly opened mouth of the train
So.......
here I am on the Piccadilly line train to Kings Cross
