tl;dr Silent girls are not what they look.
I take evening classes; that class has assigned seating. One day, I found a post-it note with a number stuck in the desk compartment. I crumbled the note threw it. The next day there was another note; now it had a girl’s name, number & #dontThrow. I recognized the name; she was the quiet girl of the class; she spoke to no one. I texted, told her you could talk to me directly instead of shitty mind games. She responded, where is the fun in that! I smirked, I am sure she was observing me from the other corner. We texted back and forth. I don’t talk much, but when I do, I can move mountains with words. She would text with generic small talk shit, I would respond to it. Only when she asked the right questions, I would react.
