Darken World

Then there was darkness with absence of light,
Some animals adjusted to the useless sight,
using their smells and touch to get around,
the ears grew larger to hear every sound,
using fingers to grab and to told,
with no light means no heat when gets cold,
thick fur pushes from smooth skin,
the hair grows thicker when used to be thin,
a ticking sound made from mouth to hear,
almost like seeing the object appear,
adjusting to all nature throws,
but if the light came back no one knows.
