Mexican Proverb of the Day: “People only approach the prickly pear cactus when it has fruit.” A timeless lesson on opportunism

Mexican Proverb of the Day: “Al nopal solo se le arriman cuando tiene tunas,” translated as “People only approach the prickly pear cactus when it has fruit,” is a recognised Mexican proverb that uses the image of a fruit-bearing cactus to describe people who approach others only when they need something. The Mexican Consulate has included the saying in its material on Mexican proverbs, explaining that it refers to those who turn to others only when they are in need. The Academia Mexicana de la Lengua has likewise been cited for the same interpretation.

When interest appears only when there is something to gain

“People only approach the prickly pear cactus when it has fruit” draws a sharp distinction between genuine relationships and those based primarily on convenience.

The image behind the saying is simple. A nopal, or prickly pear cactus, can stand quietly without attracting much attention. Its spines make it an unlikely plant for someone to approach casually. But when it produces tunas, its edible fruit, the situation changes. The fruit gives people a reason to come closer.


The proverb applies that image to human relationships. Someone who is ignored when they have little to offer may suddenly find themselves surrounded by people when they acquire something others want.

Success can change who comes calling

This behaviour can become especially noticeable when a person's circumstances improve.

Someone who gains financial success, professional influence or social standing may discover that people who previously showed little interest suddenly become friendly. New invitations may appear, old acquaintances may return and requests for assistance may increase.

The proverb suggests that such attention should not automatically be mistaken for genuine affection.

The important question is not simply who appears when circumstances improve, but who was present before there was anything to gain.

Genuine relationships are tested in difficult times

A relationship built on mutual care does not depend entirely on what one person can provide.

Friends and relatives may remain supportive when circumstances are difficult, when there is no obvious benefit to them and when helping requires time or effort. Their presence is not conditional on receiving something in return.

That does not mean every person who asks for help is acting selfishly. People naturally turn to others when they face difficulties, and asking for assistance is part of healthy relationships.

The warning is directed at a repeated pattern in which someone appears only when another person's circumstances make them useful.

The difference between friendship and convenience

The proverb encourages people to look beyond appearances.

A person may receive considerable attention after achieving something important, but that attention alone does not reveal its motive. Some relationships grow because of shared experiences, trust and affection. Others may become active because one person has acquired something desirable.

Recognising the difference can help people understand their relationships more clearly.

The saying is therefore not simply about distrust. It is also about paying attention to consistency.

Why the cactus makes the lesson memorable

The strength of the proverb comes from its everyday imagery.

The nopal is associated closely with Mexico, and the tuna is its fruit. The contrast between the cactus and its fruit makes the message immediately understandable: the plant is suddenly worth approaching when it has something desirable to offer.

That physical image becomes a metaphor for human behaviour.

The lesson does not require a complicated explanation. People can recognise the pattern in ordinary life because most have encountered situations in which someone's interest appears to increase when there is something to gain.

The value of recognising opportunism

Being aware of opportunistic behaviour does not mean assuming that everyone has hidden motives.

Instead, the proverb encourages a more careful understanding of relationships. It asks people to consider whether someone's interest remains when circumstances change.

If attention disappears as soon as the benefit disappears, the relationship may have been based more on convenience than genuine concern.

That realisation can be uncomfortable, but it can also provide clarity.

The timeless lesson

“People only approach the prickly pear cactus when it has fruit” offers a memorable warning about relationships built around self-interest.

Its message is not that receiving attention after success is necessarily a bad thing. Rather, it suggests that people should distinguish between those who value them and those who value what they can provide.

The most meaningful relationships are not defined solely by what someone has to offer at a particular moment. They endure through changing circumstances and do not disappear when the fruit is gone.

The proverb ultimately leaves us with a simple test for genuine connection: pay attention not only to who comes closer when life is rewarding, but also to who stays when there is nothing to gain.
