Though a cursory listen to "Goodbye Cruel World" might lead one to believe that Pink is on the verge of committing suicide, the song is actually more about metaphorical rather than physical death. Having decided to isolate himself completely from the external world, Pink sings his final farewell to the world outside and the life he knew as he arranges the last few bricks in their places. As Waters said in his 1979 interview, Pink is "going catatonic, if you like…he's had enough, that's the end." Unlike its counterpart, "Outside the Wall" (which shares the same root music), "Goodbye Cruel World" abruptly ends as Pink sings the last goodbye in almost a symbolic placement of the final brick, instantly cutting out the outside world (the listener included…at least at the moment). The abruptness of the ending also implies Pink's willingness to utterly leave the world behind and take refuge where no one can reach him.

Just as the first half of the film includes shots of riots in an attempt to bring about closure to this stage in Pink's life, the beginning scene for "Goodbye Cruel World" reintroduces a shot already familiar to the audience, that of the catatonic Pink watching TV (magically unsmashed) with a cigarette burned to ash all the way down to his fingers. The shot creates a time arc, linking the beginning of the film with the end of the first half, reestablishing the present state of time and showing that all that has happened in between "In the Flesh?" and "Goodbye Cruel World" were in the past. The reintroduction of the scene into the movie shows that Pink had already completed his wall even before the audience came into the album and the movie, possibly creating an overall sense of futility in the audience as we helplessly watch the events that have already taken place. Also note how the final three shots of the "Goodbye Cruel World" offer a reversal of some of the first shots from the movie. While "When the Tigers Broke Free, Part 1" began with a shot of the playing field, then cut to a close up shot of Pink's cigarette before panning backwards to show Pink, then zooming into a close up of his eye, "Goodbye Cruel World" is the very reverse, going from the cigarette to Pink to Pink's eye to the memory of the playing field. And so the first half of the film ends with a reversal of its beginning, quite possibly alluding to the regressive decay Pink is undergoing at this point in his narrative.

The playing field scene takes on a slightly more significant role at this point in the movie in that it plays longer than before. Whereas the shot shifts halfway through Young Pink's traversal of the field during "When the Tigers Broke Free, Part 1" he makes it across the field in "Goodbye Cruel World," stopping and looking down as presumably finds something on the ground. Though many questions abound, one in particular occupies the top of the list. Why is it that Pink thinks of this one moment out of a lifetime of moments the very second he imprisons himself behind his wall? What is it that he finds here in this childhood memory that has affected him so much as to be his sole thought when faced with self-imposed isolation? I suppose you'll just have to continue reading. Fortunately for the audience, this is only the conclusion of the first half of Pink Floyd's monumental work of art. The characters have been introduced, the foundation has been laid; now it's time to venture into the unknown.
