The lyrics to The Black Keys's song "Lonely Boy" tell the story of a man who is above the person he loves but still chooses to love them regardless of their flaws. The repetition of the line "any old time, you keep me waitin'" emphasizes the frustration and disappointment the narrator feels in his relationship. He acknowledges his loneliness and the pain of waiting, but he still clings to the hope that his love for this person will be worth it in the end.

The line "your mama kept you but your daddy left you" is a reference to the idea of abandonment issues and feeling like you've been left behind. The narrator questions whether he was born to bleed, implying that perhaps it's just his nature to go through pain and heartbreak in love. The chorus "I'm a lonely boy" shows that despite the love he has, he still feels a sense of isolation and sadness.

Overall, "Lonely Boy" is a reflection on the complexities and emotions of love, and how it can bring both joy and pain. The repetitive nature of the lyrics emphasizes the monotony of waiting for love and highlights the frustration and longing that comes with it.
