Your teacher hasn't taken much poetry to the classroom, but songs are poems, you know.
Talking with Pablo Garcia, another teacher,the idea came to me. In fact he showed me a poem by Benjamin Zephaniah. I looked for him in Google and found a treasure!!!

Enjoy this example and go for more poems by him on the title.

Until I became one of them.

Watch the use of capital letters.
