I've seen people indent their poems like below:
Writing on wall
It was just plane writing on wall
I must have taken it a serious call
She was on and off repeating same thing
There was hidden message through somethingThere may be long wait
All dependants on fate
How can one think and rate?
It is difficult to state
Or I've seen some like this:
Writing on wall
It was just plane writing on wall
__I must have taken it a serious call
She was on and off repeating same thing
__There was hidden message through somethingThere may be long wait
__All dependants on fate
How can one think and rate?
__It is difficult to state
Is there other possibilities? When should I use which?
