It's your first day at a new job and things seem to be going well. You met all your coworkers and couldn't help but notice how cute your new cubicle neighbor, Serena, is. She's a perky, nerdy girl fresh out of college, who vacillates between being bubbly and funny to being withdrawn and shy. Throughout your first office meeting, she stayed quiet, with her head down, hands in her lap, and shy blush on her cheeks. Yet at lunch, she was pleasant and talkative, making friends with just about everyone there.
