Honesty is the best policy

Everyone always says that one should be honest, at all costs. But where do you draw the line ? How do you know whether you should tell someone honestly about something you know that could save them a lot of heartache or whether you should keep it to yourself ? Strangely enough people don't appreciate honesty because for starters they think that the only reason that you are telling them something is that you have vested interests or are bitter about past experiences. And i've thought about this for a while and debated with my conscience about it and even subtly tried telling them that they might be making a big mistake. But people have a tendency to see only what they want to see. I think sometimes it's better to let people make their own mistakes. Maybe it's a part of their karma, one can't save everyone !
