Think about something you do that you don’t want anyone else to see/know you do. I don’t mean anything illegal, or even immoral. I mean something that’s simply “not done”–even if nearly everyone does it. For example, research tells us that nearly all people pick their noses, and that an astonishing majority of people (at least sometimes) smell their fingers after wiping their behinds. Choose one of these uncomfortable behaviors and then write a story–or at least a scene–in which your character performs the behavior and then discovers that s/he has been observed.
