As soon as i closed the door, i was struck in the back of the neck by something hard, likely iron or other hard metal and knocked to the floor. Realizing what had happened, and shaking off my surprise, muscle memory took over and i jumped up quickly pushing backwards into a male shape behind the door and slammed my fist into his crotch. As he groaned and bent over slightly, my knee came up under his chin and slammed his head into the brick wall behind him. Now he was mine. I came up under his chin with my right palm and, as his teeth cut off the tip of his tongue, he dropped the clock he had apparently slugged me with, and it skidded across the tile floor. As it hit, i took him by the back of the neck with both hands and smashed his face into the white porcelain sink. Bits of teeth and sprayed blood shot into the sink as his body slumped to the tile floor.
