This post is pointless, but I will give it try
I have met someone from college that is very likely a semi-dual.
We both noticed each other from afar and seemed interested in one another at first sight
We worked every monday 4 hours straight for some time last year at a embedded systems class
I thought she was a dual by the time, and I started to test her in order to confirm my hypothesis
I realized that we clicked in many ways: she could understand what I meant just by drawing instead of saying anything, sometimes she would explain ( pretty well) to other people what
I said and vice-versa, we both had written a blog at the same age (silly example..)and I know because
I stalked her on facebook, but then I told her I had written a blog, and she made a facial expression of wanting to approach me tell me something, but she told nothing about her blog (my blog was about neuroscience whereas hers was about christianity), it felt that we had the same level of intelligence (We both graded 9.8/10). We seemed to have the same upbringing, although we were very different from one another.
Why I think she is my semi-dual:
She is pretty much the ideal girl for me, everything that I expect, but we always had a clash at some point during the classes, in a way that it hit me very hard in my heart, and I would feel helpless and disappointed with my expectations (but next class everything was always fine again). Whenever I closed the psychological distance, we would clash again, and I was always wondering what was wrong.
Also, she was always being too nice in a way that seemed unbearable and fake, so I always got irritated. I sometimes saw her walking with some friends and she was either hugging or cuddling, and I thought "my dual wouldn't behave like that".
So my feelings towards her ended up being of deep care and at the same time a little bit of hate and disappointment. She seems so close to ideal, but there's always something important that I disapprove greatly in her behaviour, and I expect her to be a somewhat guarded and closed person, and more authentic.
Btw, she dresses amazingly beautifully and it seems effortless to her. I know this is pointless.
