Shadow

Shadow is a tricky thing
It changes with the light
Sometimes it's very dark and long
Sometimes it's out of sight

Shadow likes to follow you
Wherever you may go
It copies all your moves and shapes
But never says hello

Shadow has no color of its own
It's just a lack of rays
But depending on the background
It can take on different shades

Shadow can be black or gray
Or blue or purple too
It can be red or green or brown
Or any other hue

Shadow is a mystery
It's hard to pin it down
But one thing that is certain is
It's always there around.
