Why is this mission so hard

A Haiku

This mission is hard
Poems are so hard to make
I don't like poem

Limerick is too hard

A Limerick

Limerick is so hard to make
For me, it is hard to bake.
When I bake, the shape looks bad
If I mess up, I am sad
I get ready to go and wear my hat
While I go back, I saw a cat

This is at east the easiest from all of these

A Free verse Poem

This mission was very hard
Free verse poem is the easiest
I can write anything I want
This mission is easy if it only included free verse poems
