Communitcation

We all learn to speak at a young age..yet why do we found it so hard to speak to one another? When do we start to assume people know what we are thinking or feeling? I know it is stereotypically a "women" thing, but I think this a problem we all suffer from. How often do you tell your boss what is wrong with you, when they ask you? Especially if you are upset with them. When your significant other asks you "what's wrong?" how often to you answer or tell the truth? Why do we start thinking the other person can read our minds or assume they should know what is wrong? Why do we learn to speak when we can't learn to communicate? Why are we so fearful of saying what is really on our minds? Granted it feels sometimes that even when we do speak our minds that the other person is not really listening- but you end up feeling icky either way right? So why not just spit it out at least then you have a real reason to be upset.
