Write something with a secret message hidden in between the words. For example, you could make an acrostic poem using the last letters of the word or use secret code words in the poem.

We say loudly and proudly, "I will always fight!"
Louder, "I think, therefore I am!"
And here we all are, standing alongside each other in power and grace.
Not everyone can do what's right, but we will make up for it in spades.
We will never be left behind again!
Have you heard enough? Will you join us?

Secret message is the 6th word in each sentence.
