One of the most exciting elements of Purim, for many children (and even adults), is the opportunity to dress up in costumes. It is a chance to dress up as your favorite iconic character, or unlock your creative juices and design something from scratch. When wearing a costume, or more specifically a mask, one can pretend to be different people and try on different character traits for the day. It’s fun, energizing and sometimes liberating. But sometimes, as in the story of Purim, the mask is used to conceal and hide what is underneath, and that sometimes people are not who they seem.
