1974 film by Michel Soutter

Interspersed with jokes, visual puns, and philosophical discussions, the story follows the attempts of a girl who has spent the last year living outside her native Switzerland to rekindle a former love affair. When her immature young friend fails to demonstrate the requisite interest, she takes up with someone the boy disapproves of. When the boy kicks the man, the man leaves both the boy and his erstwhile ex-girlfriend to their own devices.
