The twins made a huge effort with their outfits for the conference. They dressed in not-quite-identical penguin suits. The slightly larger one had also dyed her strawberry blond hair black, making it much easier for strangers to distinguish the two sisters.
We were just about to enter the conference hall when the slightly smaller twin detected a smell that displeased her. As she turned to stomp off, the other one followed. I hoped that they would return in their own time.
Meanwhile I made it to table 6 at the front of the room with some other PhD students. Here we waited for the opening address.
