Smile

I'm looking for something that's very precious. that was suddenly uprooted
from the faces of all people in my town, even in my world.
what is it........? it is a smile
every human is created with face
on our face there are lips
that can be moved
this way (forward), that way (sideways)
and that way
but.........
what caused the people lost their ability
to smile.........?
but it will happen in
the future
