Do u think a secret can do more then give us power to say i know somthing u dont?

You are not confusing. Your question is easy to understand. Keep the power of the secret to yourself. If you brag about it to make yourself feel more important than you are still breaking your promise. You are telling that you know the answer. If this secret makes you feel good keep it completely to yourself if it is something that somebody who trusts you told you you would be betraying them. But if it is a secret that needs to be told to help somebody than talk to them about it and see if you can get them to talk to somebody they trust. Be a good friend. Number one take care of yourself!
