Shadow; it's the part of our life
Walking together with us is its part;
But, the fact is we can see it only in light, not in dim.
It's black but when we are alone it always became our soft light.
You never walk alone; you just need to find who.
when I was a kid I try to catch it but it's always;
One step far from me.
I used to cry but time goes on; time taught me it's always like that.
So, life keeps going; trust and believe in yourself; if you can do that then everything is possible.
Read again, Shadow is an example.
