She was so lonely, so very lonely. Her husband passed away just three months ago. The person she would turn to in times of such desperate need was gone. She missed him and needed the safety of his arms. She needed to be sheltered from the pain. She needed to be comforted and told that everything would be all right.
She tried the best she could to clear her head. She had just returned to school this semester. Still shaken by her troubles, she tried to continue a normal life. Calculus was just the class for her. She was forced to focus, but she still felt empty. At least the class filled empty time. Time she would had spent at home, in her empty house or at work.
She had never noticed her teacher before. She had taken his classes, starting from College Algebra. She felt comfortable with this teacher and his style of teaching. Through the years, she had befriended him, well both her husband and she.
Trying not to feel sorry for herself, she refocused on the lesson for the day. The lesson was on some obscure way of doing problems. She knew that the next lesson would cover the shorter way of doing the same task but the homework dealt with today's lesson.
