Imagine you’re waiting for a train; you’ve just flown into a new, bright city, and you’ve found the main station for the underground system, and you want to get to a particular station.
You are here to perform at an exciting Event. You have been invited by The Organisers and they have been clear to you that you are not the star of the show, but an integral contributor nonetheless. The Event is an exciting opportunity for you, and while The Organisers did not give you a specific thing to perform, or an exact time for you to be there, you’d like to get to the venue soon so that you can plan and prepare. You’d like to make something special for the audience. So you go straight from the airport to the underground station and begin to explore which train you should take.
