My head did get bumped a bunch of times when I was a kid, either because my parents were clumsy or myself being naughty, it might mess some things up in there. My parents also claimed it’s because of the high fevers I caught from one of my grandparent’s place. Then again, my parents resents each other, and they are not kind about me stuttering, they would find any reason to pin the cause of my stutter on each other.
