Not for the first time, Natalie wondered why she was still teaching.  Not for the last time, she gave up grading to simply wander around her apartment, wishing she were less concerned about her students.  It took her days to grade a simple group of essays.  Every time she received a new set of assignments, she promised herself that she would comment lightly and get it done fast, but that never happened.  Natalie commented and explained and gave pointers at every step.  She couldn't help it, and it was killing her and reducing her salary to less than minimum wage.  She thought, not for the first time and not for the last, that being a waitress might be more profitable and less stressful.
