Average, Common, Normal: What Does That Mean?

Life on mars, how strange for it to be so natural, how unnatural is for me to be so normal; things I could never be, or see, or live, or feel. I cannot feel normal, I cannot be normal, how could anyone live normal? If such a thing exists. Things beyond my comprehension. To learn is the way of living for those who are trying to move forward and succeeding at it.
