I don't mind if nobody tell me their secrets. So what!!!
Would that information be a life altering experience for me to begin with? Would it make me a better person? Would it change my quality of life? I don't think so.
Actually, I prefer not to be confided with highly confidential secrets. When you were ask by a friend to keep one he or she is holding you responsible if the information leaks out one way or another. There is too much burden imposed on a person when you keep someone else's secrets. That's why it makes me wonder, are they really concerned about their friends to let them bear their own load? Because we know, they know -- a secret would always be out in the open -- and it's human nature to scratch for the itch. When you give someone your secret it becomes a burden to that person and the natural tendency for him or her is to confide it to someone just to lessen the weight he or she is carrying.
What I hate the most is when someone talks about something, but they would never tell you what it is and instead they would say, "it's a secret!" Screw you! I really hate it when they let you know there's a secret, but they refuse to give you the detail or the key to unlock it. In that case, then they shouldn't mention it in the first place because it's also the same with saying: "I cannot trust you, you're a blabber." So, if you're not interested to tell someone your secret then it's better if you don't say anything or if you just shut your mouth and keep it to yourself. That way, everybody's calm, peaceful and happy.
