Which excerpt best reflects common features of realistic fiction?

A good excerpt from Running Man fiction for your reference:

"Ok, Mom, seriously, I’m ... Mom?"

My mother was lying in a pool of blood on the cold tile floor in the kitchen. Her brown hair and Monaco Coach work shirt were caked with blood. Her mouth was open wide, a perfect oval, blood plastered to the sides, the last of it dribbling from her mouth. The knife, was sticking out of the underside of her thigh, well actually, all you could see was the handle, black. I could only stand there and watch. My Converse stuck to the bloody floor. I stood there and watched."
