Of Parents and Children

It is the story of a father, 70-year-old retired microbiologist, and his 40-year-old son. They live alone and, apparently, the only thing they have in common is the walk they take together once a week, at the zoo, where the father gives a regular series of lectures. During these walks, they hold conversations in which love and hate are intertwined, and moments of understanding give way to moments of a total lack of empathy.
