What IS normality?
What IS the norm?
I would LOVE someone to pipe up with a numerical value for it, be it a dress size, height, weight, or some other dimension which dictates a template to which we should be. Because if you should find this magical number, tell me who it was that dictated or determined that number in the first place.
How heavy/tall/grey should an elephant be? Is a centipede with two extra legs a disgusting abomination or an exceptional miracle?
I might seem like I am being abstract here, but think about it.
The only thing we have in common is we are all human beings, right? That's it. The rest of it, we're unique. TOTALLY unique.
"I should be ten stone, I am eleven stone. I must be overweight."
No - eleven stone is perfect for a Billy/Joanne/Mick or whoever you are. You are the perfect representation and version of who you are, not necessarily WHAT you are.
