You aren't a bad person. You just aren't nice. Your parents are constantly fighting and the edge of a divorce. You learnt that yelling could get your feelings across from a young age cause they would never hear your crys over their yelling. You learnt a lot of things. That anger in the form of slamming fists against surfaces, banging doors, yelling, and flipping over chairs was normal. That was how everyone expressed anger, right? You went to hogwarts, the unusual parents wiping happy tears, and kids waving goodbye to their parents. You could only watch in silence. Cause you never knew what it was.
