Growing older, Pink is tormented at school by tyrannical, abusive teachers ("The Happiest Days of Our Lives"), and memories of these traumas become metaphorical "bricks in the wall" ("Another Brick in the Wall, Part 2"). As an adult now, Pink remembers his oppressive and overprotective mother ("Mother") and his upbringing during the Blitz ("Goodbye Blue Sky"). Pink soon marries, and is about to complete his "wall" ("Empty Spaces"). While touring in America, he turns to a willing groupie ("Young Lust"). After learning of his wife's infidelity, he brings the groupie back to his hotel room, only to trash it in a violent fit of rage, terrifying the groupie out of the room ("One of My Turns"). Pink, depressed, thinks about his wife, and feels trapped in his room ("Don't Leave Me Now"), and dismisses every traumatic experience he has ever had as a "brick" in the metaphorical wall ("Another Brick in the Wall, Part 3"), Pink's wall is now finished, completing his total isolation from human contact ("Goodbye Cruel World").
