Cover art for The Stranger lyrics by Billy Joel

This song is talking about the "real you," the one that we tend to hide in public. Since we don't see this person very often, it's called "The Stranger." I think the "storyline" of the song though would suggest that the main character was so busy being someone else that when he finally did go home to a loved one, they didn't recognize eachother. The very last verse sort of gives me the impression that some people really fear this stranger and it's desires, but we shouldn't because sometimes The Stranger is right.
