You folks are giving me battleground flashbacks. I'm actually subconsciously cringing back.
It didn't matter whether I shined the light on the moon or directly on the work, it was never right. My dad would roar, "You stupid c$=t, shine the light on the work!". Then there'd be the grab for the light, and I'd get whacked with it. Then the bulb would go out, or it would break, and it'd be my fault? Then he'd punch me and insist I stand next to him, telling me, "I need a helper, not another stupid useless c&$t like your mother.", and other interesting, but similarly themed comments. With the occasional backhand, or wrench to the face, if I wasn't wary.
The funny thing was, after I walked out, he never asked my siblings to hold the light. I'm pretty sure he just liked taking every chance he could to make me feel small, weak, and stupid.
