So by accident I met on a meetup event the flatmate of my main plate, a girl with whom my plate became quite good friends. She went to this meetup without knowing I would be there and vice-versa, but we both knew who the other was because my plate had shown pics of us to each other. The event at this bar was fun, and I chatted a bit with this girl throughout the evening. She´s in a relationship now (albeit a bad one) but the weird part came after. She acknowleged who I was, and asked me not to tell my plate that we had met, explaining that my plate wanted to be the one to introduce us to each other. But why would she want to keep this a secret from a good friend?
