Let's choose "Honesty is the best policy." This means that it is always better to be truthful and sincere, even if it is difficult or uncomfortable. Being honest builds trust and leads to better relationships in the long run.
Example: If you break something accidentally, it's better to admit it honestly than to try to hide it or blame someone else. This way, you show responsibility and give others a chance to forgive you.
A similar Russian proverb is "Лучше горькая правда, чем сладкая ложь" (Luchshe gorkaya pravda, chem sladkaya lozh), which translates to "Better a bitter truth than a sweet lie." It conveys the same idea that truth, no matter how unpleasant, is always preferable to deception.
