My roommate picked up a small white snake and said he wanted to keep it in the dormitory. I told her that snakes in the wild carry many viruses, and pets were not allowed in the dormitory, and advised her to send the snake away. Unexpectedly, this snake understands human speech, so it holds a grudge against me. From that day on, small animal parts would appear on my bed from time to time. It wasn't until I took my five-year-old sister back to the dormitory that the snake bit off two of her fingers while I wasn't paying attention. In anger, I took a fruit knife to kill it. My roommate stopped me and let the snake go. Four years later, I graduated from graduate school. As soon as I opened the door of my house, I smelled the smell of blood. When I looked up, I saw dozens of pairs of snake eyes staring at me.
