The Incident

Did I feel bad for accidentally trapping my sister in the wall? Not particularly; let me explain. 
    My sister is a witch and all she does is talk about Hogwarts, it gets quite annoying at times. When I was on the platform, waiting for her to come through, I started to explore. I had spied something in the corner, it was a lever. Being me, I pulled it; it did not do anything. Until, I heard a scream. Turning around I saw that I had closed off the way onto the platform, just as my sister was walking through. It gave her a good scare; enough to get her to stop talking about Hogwarts.
