For me, Purim always brings memories of my Bat Mitzvah year, when each student in my class was supposed to create a project about a Biblical woman.

In the text, she is guilty of nothing more than trying to preserve her modesty -- surely a role model to us all -- and yet, she is villified by the Midrash. Perhaps there was room for only one female hero in this story; perhaps the Midrash felt the need to find some justification for her seemingly unjust fate. Either way, she is certainly more sinned against than sinning...
