"Have you seen my tampons?" Matt asked. "I had a new box on my dresser and now they're gone. My period starts tomorrow and you know how heavy it can... What are you staring at?"
Jon WAS staring. Staring at Matt's sexily curving hips, miniskirt, black tights and feminine legs. He was even wearing girl's shoes. "Oh, I'm sorry, Matt," Jon recovered. "I haven't seen them recently." Technically, it was the truth; Jon couldn't have seen tampons that hadn't existed just a few minutes before.
"All right," said Matt. "Just thought I'd ask. Maybe Zoe borrowed one. Ever since our periods synchronized, she keeps doing that to me. Mom will probably let me borrow one of hers." Matt left the room, Jon continuing to stare after him. This would take some getting used to.
