Just keep your mouth closed Sometimes you feel free and say words or things to others without feeling worried . You said what you said because you thought for seconds that they will respect your speech and will keep it and won't talk about it just as you asked them to. But actually you were so wrong as simply there are no one deserves to tell him about what should still in your own secret box , Even if this speech was so trivial one. But if it was a trivial matter, so let me tell you that you're so lucky , because you knew that they will do the same for the important one , and it was a test for them. So my advice for you is KEEP YOUR MOUTH CLOSED.
