Invisible Protecting Thread

Moon is full on every full moon day

But one full moon day brightens more

Do you know why? 

To see the faults that harm the relations

The thread is thin

But it's a straight line

Because no one can join

Just likes the two sides of a coin. 

Are you thinking it's impossible? 

No yaar it's possible 

In case of the true relations

Just like the brothers and sisters.
