Mutual trust and understanding are the foundations on which a lasting relationship is built.
Elucidate this statement with reference to "The shady plot."

Mutual understanding and trust is very important for any relationship. In the lesson 'A Shady Plot', Lavinia doesn't trust her husband and takes for granted that he is having an extra marital affair with another woman named Helen. She doesn't even try to investigate the matter and believes what the Ouija board shows her. Whether it is a relationship between parents and children, siblings or husband and wife, every relationship demands trust. Without it, no relationship can survive. It is human nature to doubt people, but when we strongly love someone and trust them, we should overpower this feeling and discuss the matter with them. Only then can we build a strong relationship.?
