Re: Quiet Girl = Hard Read
I believe what Xavier means is that after you give her an ioi, back off and show a bit of disinterest in her. Make her attempt to come to you. It's just like cat and mouse.
I also really like the idea of transforming a sign of friendliness into a flirty gesture. It's great for speeding things up and taking them to the next level.
Although this might be old Swagman coming through, and I am attempting to kill that part of me right now, you should take things easy. Considering she is quiet and she is be a bit shy, she may react negatively to sudden moves. Go with the flow of things, be natural, and you should get to your destination in no time
