interviewer: What would you like to tell people?
andrei tarkovsky: I don’t know … I think I’d like to say only that they should learn to be alone and try to spend as much time as possible by themselves. I think one of the faults of young people today is that they try to come together around events that are noisy, almost aggressive at times. This desire to be together in order to not feel alone is an unfortunate symptom, in my opinion. Every person needs to learn from childhood how to spend time with oneself. That doesn’t mean he should be lonely, but that he shouldn’t grow bored with himself because people who grow bored in their own company seem to me in danger, from a self-esteem point of view.
