As a teacher of writing and literature at Salem State College, I hear a lot of stories. My students, although they may never have ventured more than 20 miles from where they were born, bring hard lessons of endurance to the classroom that seem more profound than any I'd had at their age. For years I've believed that they bring a certain wisdom to the class, a wisdom that doesn't score on the SAT or other standardized tests. The old teaching cliché -- I learn from my students -- feels true, but it is hard to explain. I'm not particularly naïve. I know that life can be difficult.
