Prov. People often enjoy illicit things just because they are illicit. To judge from the number of his extramarital affairs, John must believe that stolen pleasures are sweetest.
Also, lock the stable door after the horse is stolen. Take precautions after damage has occurred. For example, After the burglary they installed an alarm system, but it's locking the barn door, or Deciding to negotiate now after they've been fired-that's a matter of locking the stable door after the horse is stolen . These expressions of action that is useless because it comes too late have long been proverbs in many languages and first appeared in English in the mid-1300s.
