Firsrt of all; Great title! It describes the whole poem, and I love the way you have used something similar in your last line as well! A great idea. Then, I really enjoyed all the mental images you have used in your poem, such as "a stubborn mule" and "third world war", they let your readers use their imaginations, but it still tells enough not to make this poem meaningless. Also, the part where you say "at only 13 years olf you forced me to grow up", that sound so sad, so wrong, so angry! Great, all good poems make their readers feel something. This absolutely did. And then the last two verses. They completed this poem, they didn't make it feel like this person gave up. But she/ he became strong and independent. And thanked "for nothing". This was a great poem, definitely worth a recommendation. (:
