A Purim play was put on in the yeshiva, with the main characters being Moredechai and Esther.  “Playing the role of Haman is easy, R’ Yoself Yozel Hurwitz commented, “for everyone has a touch of arrogance and cruelty.  But to live up to Mordechai’s midos is very difficult, so it takes special effort to imitate them.” ~ Sparks of Mussar
