Este book comes to collect, in a delicate version in literary prose, some lessons that Juan Luis Trillo was substantiating above all in partial oral stories. It is gratifying and useful that a professor, on the return of his years at las tables with students, sublimates his thought as it happens here, because in this way he transmits to those who sat with him or to those who are now doing so for the first time his ideas in a polished state of purification.
