"Cross That Line" is a song by English musician Howard Jones, released in 1989 as the title track of his fourth studio album. The song delves into themes of personal responsibility, maturity, and the consequences of our actions. The lyrics emphasize that it is not the singer's fault if someone fails to live out their youthful dreams. The person in question now wants to backtrack and realizes how different things have become. The song alludes to love being like alcohol that evaporates before our eyes, suggesting that once strong and cherished bonds can turn into chains that we despise. The chorus warns that once someone crosses a certain line or boundary, there is no turning back and they cannot expect the singer's support or forgiveness. Taking responsibility for one's actions becomes crucial, even though the grass on the other side may not always be greener. The lyrics indicate that finding out the hard way can be an ongoing struggle, but the singer wouldn't dare stop them from experiencing it. The bitterness has left the singer's words, and now they use tears as a way to cleanse their soul and start anew, free from destructive emotions. Ultimately, when someone crosses that line, which could refer to a personal or relationship boundary, there is nothing more to say or do. The individuals involved are no more, and the singer asks for help in explaining these sentiments and feelings. Overall, "Cross That Line" explores the themes of personal growth, accountability, and the irreversible consequences of our actions. It highlights the importance of taking responsibility and understanding that once certain boundaries are crossed, there may be no way to repair the damage.
