This song seems to be about a lack of communication in a struggling relationship. One where a significant other has done everything they could do to make someone smile, but they never smile for them, leaving them fed up; They plead to know why or what they can do, repeatedly saying "Tell me, tell me." No matter what they do to get a signal from them, they'd be lucky if they'd ever wave in their direction, and end up accepting that this relationship cannot be salvaged.
