The Monet Family in the Garden.
Manet was working on the picture in the Monets' garden in Argenteuil, when Renoir arrived. The latter loved the scene so much that immediately began to paint the same thing. Manet did not like the situation and in his irritation told Monet to advise his friend to quit painting, as it was clearly not his vocation.
