Transparency started just immediately after the institution of marriage. The couple Adam and Eve were both naked before each other and were not ashamed (Gen 2:25). When a spouse starts hiding anything, it simply means that there is something they are ashamed off. Jesus himself was very transparent (Mk 12:14). His disciples knew that he was true; that he was what he said he was. If your spouse cannot read or listen to your conversations, it simply means you are not what you say you are.
“Bonyfish beware because the same net that caught the jawless fish, caught the cartilaginous fish” (Hamilton Ayuk). Beware earthly paradise seekers because there is a serpent in every paradise"(Hamilton Ayuk). "It is not how well you know a person; it is how well you treat them that they will live longer and happier with you." Idle people write, idler people read, and idlest people read and whine that idle people are taking their time (Hamilton Ayuk).
