Find the image of a mask you find fascinating (e.g. by typing into google: "mask cultural images"). Look at it carefully and try to absorb all the details.
Try to get a sense/feel of the spirit that the mask embodies. Then imagine you are wearing the mask and you are becoming the personality of the mask. Tell us about your new you in any genre you wish (e.g. story, journal entry, email message, poem, dialogue, description etc).
Do some research about the mask: culture, meaning, symbolism, cultural and/or historical and/or social and/or religious and/or mythological background and tell us about it.
This, too, is meant to be fun! Enjoy to be someone else!
