Flirting is so much fun, and Susan is so good at it. She's pretty, popular, and she has a good-looking boyfriend, John, who thinks she's the greatest. The girls in her class used to like her too, until they got sick of her always cutting in on their territory and flirting with their boyfriends. Susan says she doesn't mean anything by it, but that's just the trouble! She also says she can't help herself -- until John breaks off with her and she breaks her best friend Debbie's heart.
