I probably can not make a smile on his face,
but, I better not hurt her feelings.
I think it is important to turn off the lights when he wants to sleep,
let him sleep soundly, then kissed her forehead and left him soundly in the comfortable dark.
I think he would not know if I was not there,
Because , soundly dark nights warmer than where I am there.
after the morning comes,
he will be fine and fresh.
