What's Normal?

Someone used the word normal the other day and I got to thinking about it so I looked it up in the dictionary and it says...

nor-mal  adj.  Ordinary, average, usual; having average intelligence.  Well that's still vague. Who's normal,  and what's considered normal? Remember, I work in a Hair Salon... I see it all and I hear it all. So what I consider normal isn't what you may consider normal. I'm not normal (if you know me you probably will agree), got friends who aren't normal (but as weird as some are I luv them), then there's family (shouldn't have to explain that one, we all got some of that), man my dogs aren't normal (ones a head case, the other a genetic nightmare). Guessing the sign hanging at the place I work is probably the most accurate than.
