Normal is...

There are all of those sayings, well maybe there is just one saying, you know that one "normal is just a setting on a washing machine"?
What is "normal"?
There is no way to define normal, is there, really?
And even in the book title, Define "Normal" the Normal is in quotes.  And I know I have made air quotes around that word when speaking it aloud.
This book reminded me a bit of Don't You Dare Read this, Mrs. Dunphrey.  But not in that I was bored or feel like I didn't need to read it.  It was different enough.
This was very good.  And addressed the fact that every one has their own pain and problems and we can't rate or rank pain.
