"I stipulated that all the characters' genders and names could be changed according to the groups' needs. John could become Jane, or Leah could become Lee. I reasoned that there isn't the huge gap between men and women that we like to think there is. We are different, yes, but our similarities far outweigh our differences. One quite angry youth leader took me to task over this, insisting that girls and boys were practically different species, and this could never work. But the interesting thing was that, with all the different cast configurations I went on to see, I forgot the original sex of the character I'd written within 10 minutes."
