NORMAL????

After a student posted on Facebook about his professor not wanting him to use the word "normal," I replied: 

What is "normal" and "abnormal?" The explanation will depend on who is answering the question.  

However, one thing is for sure... "normal" is a very subjective characteristic used to describe something or someone. My "normal" may be your "abnormal" and your "normal" may be my "abnormal."  Does that mean that there is no such a thing as "normal?" One may argue that what does not exists is the "abnormal."  Since we all have a different view of what "normal" is, doesn't that mean that we are all "normal" and the existence of the "abnormal" is what makes us all "normal."
