Ever experienced this kind of abuse?
As a kid (and a very unhappy one), sometimes my witchy mother would get very angry and she'd grab me by the forearm and whirl me around the room while screaming at me. She wouldn't beat me up--the furniture would do that! I'd always feel it was basically my fault for being clumsy and tripping over the furniture or banging into it. Often these incidents would end with me becoming so dizzy I'd just fall down in a heap and be too dizzy to get back up again while my mother stood there laughing at me for my idiotic helplessness.
