Honesty is the best policy

Мнение автора +-
In my opinion, honesty is always the best policy. (+) Firstly, if a person is tended to develop communication with other people based on the truth, he or she (they)can count on honesty in return (это не совсем точный аргумент – так как не отвечает на вопрос почему honesty – the best policy)
Secondly, an honest person is much more succeeded (is more successful ) in building any kinds of relationships, because, for example, friendship and love cannot exist without honesty. (+)

Personally, i disagree with above-mentioned opinion. A long-term lie can be much more harmful to feelings, because any untruth will be uncovered anyway and can lead to full break-up with people who trust you. Rebuilding former relationships may not be possible
