She takes the microphone and taps it with her finger to make sure it's on. She pushes her hair behind her shoulder, takes a deep breath and nods to the man at the soundboard. She looks down at her shoes, grits her teeth and when the words pop up onto the screen, she opens her mouth and starts to sing the first few words of "Like a Virgin." She's hesitant at first, but soon the cheers and whistles start. Her bravery grows. Someone in the crowd lets loose with a catcall, and she rewards them with a little shimmy. The audience goes wild. She starts a little strut, a little dancing comes over her, and soon, she's channeling Madonna. Before long, she isn't just singing -- she's doing karaoke.
