Bai Juyi - After Lunch

After eating lunch, I feel so sleepy.
Waking later, I sip two bowls of tea,

then notice shadows aslant, the sun
already low in the southwest again.

Joyful people resent fleeting days.
Sad ones can't bear the slow yers.

It's those with no joy and no sorrow—
they trust whatever this life brings.

Bai Juyi
