I ran swiftly towards the train while pulling my ticket out. I had a meeting on and had to be early. On the train I sat down next to a man with the exact same bag. It was an awkward silence between us for the whole trip. When I arrived, I took my bag and left the train. It was heavier than I expected. I went inside and they were all waiting for the paperwork. I checked my bag and found rocks inside. I was confused. They became irate when I told them I took the wrong bag on the train.
But why was the other bag full of rocks?
