Mariz, how can the plight of such a drunkard ever improve, when even his advisor laughs at his vows of repentance?

This couplet by Mariz paints a poignant picture of a person deeply entrenched in a habit, specifically excessive drinking. It asks how someone can truly improve when even those who try to offer guidance can't help but chuckle at their promises of repentance. It suggests that this person has made so many unfulfilled vows to quit that their sincerity is no longer believed. The poet implies that when even the well-intentioned lose faith in one's attempts to change, the path to true reform seems incredibly difficult, almost impossible, for such an individual.
