Smiley faces

The one that makes and encourage others to squeeze the lip upwards for a smiley face... Somehow in the middle
Of the night, can't smile yet not crying.

It just lack of something to fall asleep comfortably. It is odd and weird for the eye and finger is still moving by now, as should be in the dream land instead.

Not to ask why, but think how? Now I just don't have any clue for that. HOW?

Can't even know where to start the question for the why and how.

The only think I know it will be a panda tomorrow morning.
