Trust is the most precious characteristic that a person can possess. It is an abstract psychological idea that a person is dependable, with behaviour that can be predicted, and who can be relied on no matter what. It is the essence that binds relationships, whether they be romantic, friendships or business. It creates a sense of confidence and security, which is most crucial in times of crises. Trust also creates vulnerability, leaving a person exposed to possible damage, whether psychological or material. Trust may be betrayed by words, actions or failure to act when called for. Once betrayed, it is almost impossible to regain. People may reach a new understanding, however at least some doubt will always persist, and the relationship will never return to what it was.
