‘People Only Approach the Nopal When It Has Prickly Pear Cactus’
The nopal is a noble and resistant plant, capable of surviving in low humidity and exposed to the strongest heat. Its thorns and the environment it grows to mean no one comes close to it.
Nobody waters the nopal; nobody takes care of it except in the season when it bears fruit.
This popular saying is used to point out people who relate only for convenience.
