Shot of truth serum, anyone? Speak from the heart and steer a relationship back into smoother waters. While you’re nervous about rocking the boat, honesty is the best policy for this pairing today. The truth comes with a disclaimer though: If you dish it out, you’ll need to be able to take it too. Once you’ve said your piece, the other person may also be candid with things that might be hard to swallow. Stay off the defensive and you’ll grow—as an individual and a partner.
