Leave me alone and don't bitch about it!!

Why do people find it so difficult to accept introverts? Why is it so difficult for people to understand that sometimes all we want to be is alone? We have to adjust to live in this world where people ask you stupid questions you don't want to answer, we have to talk to people we do not want to talk to on daily basis and we deal with it. So why is it so hard for you to just come to terms with the fact that when once in a while we tell you we just want a me day? Why do you have to make a big deal about it like for some reason it's a cop-out? I don't give you attitude when you blow me off to hang out with your boyfriend, or go to some party or whatever. So don't give me attitude when I tell you that I want to be alone, that I need to be alone. It is really not that hard to understand, you don't have to know how it feels to like having some time just for yourself all you have to know is that some people like it and you should respect that.
