Why Hide Things or Not Be Totally Honest?

PERSONAL RANT- DON'T READ IF YOU REALLY DON'T KNOW ME THAT WELL PLEASE!
I HAD A VERY BAD WEEK!

I don't know how many times people think they can get away with not telling you how they truly feel or what they need to say. I mean why not just be up front and say hey this is the thing. No instead they think they can not "hurt" you or can deflect things to make themselves look like they are the ones with the problems. You know the old stand by - "It's not you, it's me." Oh come off it. We see through that. Grow up and realize people know what you are saying. Or is it that you are afraid of getting hurt. Oh well that would not be my problem that is yours. I guess as I have realized in my life people are not there to help you as much as you may think. They are there to get what they want and/or need at the time. They really could care less how it may affect you or how it may make you feel. So instead they say things that they think will help you through it. Such as "we will always be friends." WHATEVER! See I can move on with out you "lying" to me and I am able to be a big girl and keep myself in check. But don't turn around later and say hey did I do something to upset you. Because we all know you really don't want the answer to that question.
