I understand your curiosity. When I think about it now, it seems almost obvious to scream for help or to bring it to someone's attention, but when I was in that situation I was (as some would say) paralyzed from shock. I was too scared to even move let alone cry out for help, especially after being struck once for making a sound. I just feel it's different when you're actually in a situation like that. At least, for me, it was.
