They're mine

What if you had mean students? And what if you loved them anyways, because they were yours? And what if after every class you went home emotionally exhausted because of how much they took from you? What if you continued to love them and to pour yourself into them even though it hurt? What if they graduated and left you? How would you feel? And what if you found them again? What if you found that they loved you too? What if?
