Last night was good . It was interesting because Diana texted me at about 6:30 saying " Dinner is almost ready ! " Although I thought she was n't getting home until 7:30 ( Metro PCS sucks and sometimes I do n't get her messages ) , but how adorable is that ?
According to the above context, answer the following question.
Who is Diana to the narrator ?


Diana is the narrator 's wife who prepares their dinner .
