Poems that can just go on and on and on.
When people are angry, they shout.
When people shout, they fight.
When people fight, they get hurt.
When people get hurt, they die.
When people die, they are gone forever.
When people are gone forever, some get angry.
This is just a short, simple example of a loop poem. The main point here is to end your poem with something that will tie back to the beginning. Length doesn't matter. It could be miles long or an inch long. Don't hesitate to try it out and collaborate!
