Sodapop is madly in love with his girlfriend, Sandy, and he wants to marry her. "Soda attracted girls like honey draws flies," but he only has eyes for Sandy. But apparently Sandy is not faithful to Soda since her parents suddenly send her to Florida to live with her grandmother. Although author S. E. Hinton never specifically identifies the reason, it is obvious that she has become pregnant, and her parents have sent her away so that she will have no further contact with the father. Even worse, the father is not Soda: Sandy has been cheating on him. Knowing the truth, Soda still wants to marry Sandy, but she refuses to read the letters he sends her, and they are returned unopened. According to Darry,
"He told me he loved her, but I guess she didn't love him like he thought she did, because it wasn't him." (Chapter 12)
As was often the case during the 1960s, Sandy's parents send her away so she could have the baby (or possibly an abortion?) without other friends and family members knowing the shameful truth.
