Green Day - When I Come Around Lyrics Meaning

I agree with a bit of what the earlier poster said. The song seems to be about the main character not being ready to change his life or his "prowlin" ways. The girl has been contemplating a break-up but apparently has self-doubts over whether or not she can survive without this guy, whether or not she NEEDS him in her life.

The guy is basically telling her to give it a shot, maybe she'll find out that the doubts were false and the relationship and he never meant as much to her as she thought they did.

The narrator/guy keeps true to his credo, though, throughout the song. It doesn't matter where he is, where he'll be found, who wants him. The only time he truly will be able to be "found," and not in a geographical sense, but a spiritual/emotional sense, is when he himself decides to come around. Until then, you just can't force the relationship if it just doesn't feel right to someone.
