How Do I Love Thee, Let Me Call You Back

Diane gets Sam a pair of tickets to a fight Sam has been wanting to see. Sam is so happy, he blurts out the phrase, 'I love you'. Diane takes it seriously and is totally taken back by what Sam had said. Diane goes to tell Sam that what he told her really made her happy, and he thinks nothing of it. Diane then proposes that they think about their relationship. If neither one of them can come up with an explination as to why they are together, Diane thinks they should call it quits. A week later, Sam and Diane still can't figure out what their relationship means, and Sam can't bring himself to tell Diane that he loves her sense he used the phrase so casually.
