Last Halloween, I went dressed as a woman. When I rang the doorbell, an elderly woman opened it, and I made a grunting noise and knocked the bowl of candy out of her hands.
She immediately called the police and told them exactly what happened. The officer pulled me aside and asked me a few questions. First, he asked if my parents were here, and I said nothing. Concerned by my answer, he then asked if I was okay, so I said nothing. He asked me what my name was, and I responded, "Hellen Keller."
When the school shooter knocks on the classroom door, and the autistic kid opens it.
One day, I was sitting on my couch watching YouTube when I heard a knock on the door. I opened the door, and to my surprise, it was my dad. I haven't seen him in 16 years, so I let him in. I noticed he had a gallon of milk in his hand, and he went to the kitchen and put the milk in the fridge.
Then he walked towards me and said, "Oh no! I forgot the cereal!" Then he walked out the door and drove away. I never saw him again.
