Every relationship is built on trust for which both the parties have worked may be for years taking care of every little thing which would build the relationship and trust. All this nurturing and trust may be blown away by just one foolish action of lying and being caught. It is like a glass shattered to pieces beyond repair. Trust that took years to build is no longer taken for granted. One would always be suspicious after such betrayal. Value your relationships not to be jettisoned by one reckless action.
