Why can't people say what they mean, and mean what they say?

Why is everyone so full of shit? Why waste everyone time? Be real, be honest, what's so freaking hard about it? I'm so sick and tired of the games people play, I mean aren't we grown ups now? What is so so hard about just saying it like it is? I mean people act like they've never hurt anyone's feelings before and are afraid to do so, I think the longer you bullshit someone you hurt them more, anyone have any thoughts on this phenomenon?
