there are two people who are doing an act at a circus.  They are in front of a huge crowd swinging from bar to bar relying on each other to keep them safe.  they have worked together in for years now and trusted no one else more than each other.  to their audience they were amazing and daring but to each to each other they were kept them alive.  they would continue to finish the show and  it was amazing.  the crowd went crazy in amazement and when the two people took their bow they knew it was their last.  they were both quitting to start a different life together.
