Expressions of affection, like putting your arm around someone's shoulder, holding hands, or giving a kiss good night, involve the principle of honesty.
Christlike communications are expressions of affection and not anger, truth and not fabrication, compassion and not contention, respect and not ridicule, counsel and not criticism, correction and not condemnation. They are spoken with clarity and not with confusion. They may be tender or they may be tough, but they must always be tempered.
Trust is the most important part of a relationship, closely followed by communication. I think that if you have those two things, everything else falls into place - your affection, your emotional connection.
