Roses and thorns are parts of the same plant. Somehow though, some people are concerned mainly about the roses. The rose is not on the plant for more than a week, but the thorns are there forever.Roses are teaching that the beauty of life will bloom, once you have taught yourself the lessons given by living with the thorns.
I would not have majored in English and gone on to teach literature had I not been able to construct a counterargument about the truthfulness of fiction; still, as writers turn away from the industrious villages of George Eliot and Thomas Hardy, I learn less and less from them that helps me to ponder my life. In time, I found myself agreeing with the course evaluations written by my testier freshman students:'All the literature we read this term was depressing.' How naive. How sane.
Teaching is a sacred art. This is why the noblest druid is not the one who conjures fires and smoke but the one who brings the news and passes on the histories. The teacher, the bard, the singer of tales is a freer of men's minds and bodies, especially when he roams without allegiance to one chieftain or another. But he is also a danger to the masters if he insists upon telling the truth. The truth will inevitably cause tremors in those who cling to power without honoring justice.
This is precisely why I being a teacher! Young people are so infernally convinced that they are absolutely right about everything. Has it not occurred to you, my poor puffed-up poppinjay, that there might be an excellent reason why the Headmaster of Hogwarts is not confiding every tiny detail of his plans to you? Have you never paused, while feeling hard-done-by, to note that following Dumbledore's orders has never yet led you into harm? No. No, like all young people, you are quite sure that you alone feel and think, you alone recognise danger, you alone are the only one clever enough to realise what the Dark Lord may be planning.
