The twin sisters' friend, Mary Miller, has been getting along wonderfully with Caleb. After Caleb overhears Mary telling her friend that he will propose to her soon, he tells Mary they can never be married.
Mary wonders if something in Caleb's past is holding him back, or whether, as her friend suggested, he would prefer a slimmer woman.
Mary had never seen her size as a problem, but thinks that must be the reason Caleb has changed his mind about her. Will Mary ever find someone who appreciates her just the way she is?
