In the new Black Keys album “El Camino” the first track “Lonely Boy” Dan Auberach sings “I got a love that keeps me waiting.”  Similar to Mr.Knightley’s long relationship with Emma, he is left waiting for her to mature into her emotions.  The constant repeating of the chorus “I’m a lonely boy” and “I got a love that keeps me waiting” reminds me of Mr. Knightley’s constant disappointments with Mr. Frank Churchill and Emma’s other love interests.
