Becky hoped Tom saw what she had written before her teacher did.

Mr. Smith was notoriously tidy about the things in his classroom. Desks were wiped down once a day, not by the school janitorial staff but by him personally. In other classes she knew friends who would write on the desks, leaving messages for the students who sat there after them - a sort of school texting service between students without cell phones, but Tom took only this one class after her. Would he see her message? She could pass it off as a doodle and if he said nothing, she'd know he wasn't interested...

unless Mr. Smith cleaned the desk first.
