What does this mean? (Brown Haired Girl)

I'm back on here again to ask for relationship (or lack there of) advice. I was the one who wrote the Pink Haired Girl and Blue Haired Girl posts. Ok so this girl and I just recently became friends. We have a lot of mutuals and were on the same teem last year. Our school splits every grade into 3 teams that you almost exclusively have classes with. The separation is so ridiculous that we're in the same cafeteria, but can't sit together. 🙄 We do have choir together, and sit next to each other twice a week. In real life we've had some casual but personal conversations if that make sense. One example is that my other friends and I are trying to get her to come to our school's GSA. As I was walking with her to our next classes she was asking me how to lie to her parents, and how. Since then she's continued to open up to me during our 2 minute walks. Texting is a completely different story. I always start the conversation, and she rarely contributes more that a three word answer. What does this mean?
