Eleanor and Reggie, the collision of lifelines.
To me this movie is about the randomness of life, how single unpredictable incidents can throw our "lifeline" onto a completely different trajectory, leading to completely novel experiences.
My own definition of a "lifeline" is a 4-dimensional imaginary line for each of us, it represents exactly where we are in space and in time. This story deals with Eleanor's and Reggie's lifelines. They each are on trajectories that likely would never meet, then something happens to Eleanor, her boyfriend fails to come home one night, the next day he starts an argument where she works, she gets fired. It had to happen that day.
At the same time something happens to Reggie, his nanny abruptly quits right before mom is to take a trip to China, she is desperate, she hires Eleanor on the spot. It also had to happen that day.
So each of their lifelines gets changed to set up the collision of the two.
The third part of this random meeting of course is the compatibility of spirits, Reggie and Eleanor. They find something in each other that they found in no other. So while it is a growing experience for each, and a springboard to different, hopefully a better lives, none of it would have happened if it had not been for the random events which led to the collision of their lifelines.
