In 1924, Monet recalled: "During the sitting, Renoir arrived. . . . He asked me for palette, brush and canvas, and there he was, painting away alongside Manet. The latter was watching him out of the corner of his eye. . . . Then he made a face, passed discreetly near me, and whispered in my ear about Renoir: 'He has no talent, that boy! Since you are his friend, tell him to give up painting!'"
Renoir and Manet both gave their pictures to Monet.
