Under orders again

I went to see my physio
And a 4 letter word she uttered
You can't say that word to me
I'm speechless, devastated, gutted
I've never heard anything so disgusting
I said abruptly and out loud
Have I ever done anything to hurt you
No! I have always been honest and proud
She did not get flustered
And was very matter-of-fact
When I stood on the scale
And she said that I was fat
Then she spoke that word
And everywhere went quiet
It no good avoiding it
You now need to diet
