When I was in highschool I had a girl go on and on about how much she loved Star Wars. I was into Star Trek and thought she was trying to annoy me. After graduation I he friends told me she was into me and wanted to hang out.
I had a different girl ask me to teach her D&D. I invited her and one of my friendliest players over and proceeded to run a simple session. She didn’t seem to want to learn the rules but kept asking me questions and listening to me intently. She basically ignored the other player. I finished that session super confused. Later she asked me to come to her house to see her new bikini top and it all clicked.
