As I was walking to college, I felt I could help students improve English by mentoring them. By utilizing my break time, I could contribute at least a little, I thought. I decided I would take only one student as my mentee. The mentor and mentee would work extra time at their will. If there would be more than one interested students, I would hold a lottery to select the participant. So I announced this in the class. Three students raised hands. I had to hold a lottery.
