A short story character of mine just said in my head.... 

'I know there is purification in suffering but by all that's fecking holy don't give me cramps that could drown a whale then make me allergic to painkillers...'

its gonna be a good story....

(yes this happens all the time, and I have to hurriedly find a pen, I have once written a thought down in kohl eyeliner on a tea towel.)
