I read this book sometime between 6th and 8th grades, so between 1976 and 1979. It was not great literature but catered very much to pubescent and pre-pubescent girls. It was a mass-market paperback anthology of short stories, and I think they all dealt with romance and/or the characters’ first kisses. There might have been some that were just about the trials and tribulations of being that age, but if so, I don’t recall specifics. I do remember one of the stories mentioning chocolate pudding. In another -or maybe the same story- the protagonist went on her first date (possibly a school dance?), and when she and the boy walked home, he kissed her, and she said his lips tasted sweet like Coca-Cola.
