Letters in time

Letters in time isn't just like any other book, it's about a girl named Rebecca. Rebecca is quiet, sullen and very sarcastic. She doesn't talk to alot of people but she does observe them. The way they talk , the way they act towards themselves and others, and the way they put a fake smile on their face. As far as Rebecca knows mostly everyone around her, but never spoke or said a word to anyone. Each week she would put a letter in envelope with someone's name on it but, no ones knows that Rebecca was writing these letters nor did anyone receive these letters. She had so much to say to everyone but when she tried to speak, words would never come out until someone new came along. She had no words to write on paper towards this person nor an envelope to provide with their name on it. Would they scatter Rebecca's silence or would Her name be printed on an envelope?
