When a woman brings up details from past conversations you had, she's been thinking about you. She wouldn't remember and mention those moments unless they stuck with her and mattered.
Okay, the next subtle sign she's thinking about you is that she brings up past conversations. This, the fact that something you've talked about stayed with her, that she remembered it, goes to show that it mattered to her and that she's been thinking about it. I mean, she's not really gonna bring it up if it doesn't come to mind, right? This can be past conversations you've had, but it also could be maybe something that you've told her, like an event or something that mattered to you.
