" I hug my pillow and do not speak a word;
In my empty room no sound stirs.
Who knows that, all day a-bed,
I am not ill and am not even asleep?

Turned to jade are the boy’s rosy cheeks;
To his sick temples the frost of winter clings….
Do not wonder that my body sinks to decay;
Though my limbs are old, my heart is older yet. "

― Bai Juyi ,
