Should your family have a secret code word system?

There are potentially many types of scenarios where you might need a codeword, I will name only a few: child feeling unsafe, a potential rape situation, a natural disaster, a riot, a kidnapping, a ransom scenario, a hold-up, extortion, robbery....well the list goes on.The codeword should be easy to remember, the military uses a running password when coming in from patrols....so this is right up your alley. Incorporate it today, and if you have young children, it is absolutely necessary. I would even run 3 different passwords, #1 I'm safe but need picked up, #2 I'm safe but it could get bad quickly pick me up asap , #3 I'm in danger call police and come get me NOW! But you decide. If you do use one now, share your story how it has helped or saved someone.
