Most couples have experienced a long and awkward period of silence after a row it is unlikely to compare to a husband and wife who have not spoken for two decades - but continue to live with each other.
Otou Katayama, from Nara, southern Japan, continues to live with his three children and wife, Yumi, who perseveres in making conversation with him but has only ever received a nod or a grunt in response for 20 years.
The Japanese couple's silence was revealed by their 18-year-old son Yoshiki, who wrote into a TV show asking them to fix the situation as he had never heard them have a conversation.
