Well, about this painting, it’s quite interesting

Four young people appear to be taking drugs in a forest. This suspicion is at odds with the ambiance of the attractive forest and sunlight filtered through the trees. An integral part of the painting is a poetic declaration which implies a risky experiment. It entails a statement of the absence of loneliness. However, the painted protagonists appear to be entirely lonely; they do not even notice their own presence. If so, they only have themselves to thank for their lack of loneliness.
