"&& It Is So True"

&& It is so true when they say "those who say they love you don't know you at all and those who say they know everything about you, don't know the smallest things about you".
Why can't they tell the difference when your sad that when your mad? Or when you need to talk about your feelings, why do they try to get mad at you and tell you your feelings are wrong or just change the subject like they dont hear you or even care?
How can they want to hear all the bad things about your life but not learn from them and completely ignore your good qualities but remembers everything bad, like what makes you mad, cry, or sad?
Why would they make you angry when they can clearly see that your already hurting? Or tell you how they feel without considering your feelings, and wont let you get one word in. And when its time for you to talk they get mad and are in denial because there is no way that they are ever wrong or could ever do anything to hurt anyone because they are so perfect and dont have any flaws??????
Why cant the ones who say they love you, know you?
Why cant they tell you waht matters the most to you?
Why cant they see when your unhappy?
