Auto pilot, mindlessly slowly going through life as if we are a self-controlled puppet.
Awaken, get a cup of coffee, go to work, come home, etc. Not a very surprising life until something ends or breaks.
Surprises. The stuff that life is made of. Unexpected pregnancy, death, loss of job, and we are startled into a "reality check" reevaluating everything we do and wondering what we have done with our lives.
