The meaning and story behind Buddy Holly's song "Don't Come Back Knockin'" is about a person who has been hurt and disappointed by someone they loved. The singer realizes that the person they were in a relationship with is a wanderer or "rover" who constantly seeks new love interests. The singer compares this person to a talent scout who is always looking for something new. The singer decides to close their heart's door to the person and refuses to let them back in. They have had enough of the constant heartbreak and disappointment. The chorus emphasizes this by stating that they won't be home and don't want the person to call or knock on their door anymore. The lyrics reflect the hurt and frustration of someone who gave their heart fully to someone who couldn't appreciate or be satisfied with their love. The song suggests that true love is a precious treasure, and the person who constantly moves on from one relationship to another will never experience the depth and fulfillment of it. Overall, "Don't Come Back Knockin'" conveys the pain of being let down by someone who continually seeks new love interests rather than staying committed.
