What Exactly Do They Mean By "Normal"?

Working in retail, I get the opportunity to meet all kinds of people.  I love working in the public and feel like I am a much richer person for it. (no pun intended).  Shortly after I started my job, I began to notice how very different people are.  I have seen a thirty some year old woman that only has the mind of a 7 or 8 year old, the old man that could not even hear what I was saying and if he could, he couldn't understand what I was saying, the woman in the wheelchair that sits outside and waits for someone to open the door so that she can come in, and the woman that has two children to hold on to and doesn't act as if she could control just one of them....to only name a few.  This has gotten me thinking...what exactly is normal and who decides who is "normal" and who isn't?  One may say that a man and a woman with  two children, a modest home, and two good jobs is normal.....or that a professional with lots of money, their own place, and a fancy car is normal.  One also may think that the overweight and "under-beautiful" person is considered abnormal.  Myself, I am here to say that I disagree with this.  Since there is not a book that tells us what the conditions for being normal are, and they don't teach a class in what is normal and abnormal as far as life goes, I am here to say that I think that all people are normal.  I am not quite sure why we started looking at other people as if they are "different", "abnormal", or a "spectacle",  but in todays society this has become common practice.  I pray that God show me to look at people not for their differences but for their likenesses.  We are all created by God, human beings, and each one of us are special in our own way.  Each one of us has a purpose lest the life that we lead be in vain.  No, we are not exact replicas of each other but how much more pretty is two roses when you add a group of different flowers in the vase...what a variety!
