WOW! to LIE

I just post to my fb that humans have this predisposed genetic factor about them for lying. Most people tell lies every single day. I however dont feel that its important to hid the truth no matter how much the truth may hurt. If I dont agree or state the obvious to me thats not really lying. But to know the truth that someone seeks and to bluntly lie about that truth is wrong. I have always took pride in finding the truth in others. And now I see that sometimes no matter how hard you try, no matter how much love you can have for another person. The truth is sometimes never told! It hurts me more to hear your lies than it ever could to hear your truths. Why cant people just be honest.. its really not that hard of a concept. Is it? I mean to know how someone feels I mean really feels deep down in their heart is truth. To not know and keep them guessing would be a lie? If that is the case I guess I am lied to every single day by the one person I hoped would always tell me the truth.
