Talk about siblings part 1

During our 5th period, our professor was absent so everyone thought it was free time already. Some left our classroom, and some, like yours truly, stayed. A few minutes later, Otto went up to me and sat at the seat in front of mine which belonged to Sabrina. She might have gone somewhere. And so sits Otto. We were speaking in Nether so no one actually understood us when we were talking. Suddenly, he opened up a very weird topic. He suddenly went like "How's your twin? Is it a girl or a boy? What are your differences?" It was really frank of him to ask the question, but I was curious about his too, so I answered back with a "I'll tell you mine if you tell me yours. Deal?" He went for the deal. I told him that my twin was a girl. Her name is Sahara, and the obvious difference between us is that she has short hair and I have long hair. She's also a little soft spoken and always displays a dissatisfied look on her face. As though she is angry or something. But she isn't. I told him to judge me and he said that I display a smile all the time and I'm easier to approach. Those actually surprised me. Sahara wasn't really the approachable type. But would you believe it or not? She's actually friendly. Even friendlier than I am. She was the reason I knew Merilee and Erika. And all her other friends. Do we agree with each other? Of course we do, we're best friends, me and her. Then I went on and asked Otto about his twin. He said that he had a brother. His name was Matrix. And all he told me is that he's paranoid. He never mentioned anything else. I paused for a bit and thought... Since this IS Otto's twin we're talking about, he's probably more industrious than Otto himself. Otto is a lazy man, as far as I have seen. He never actually did anything at our dormitory. Matirx could also probably be more prone to displaying his emotions since Otto doesn't. He always has that still face. All the time. And judging from what Otto said, his bother being Paranoid. He might be extra suspicious of people around him. What a funny chap. We were laughing about it when Vanilla suddenly interrupted. She was shocked to see Otto laughing and found it really curious. She went like "Whoa, Otto was laughing back there. What were the two of you talking about?" And that question leads to part two of this blog post...
