Oh Merlin of course she knew who he was. How could she not?! But she just smiled and moved on like it was nothing. She was starting to head over to the gardening section and point him in the direction of the books he was looking for when he thanked her. That was surprising. She turned to him and smiled, "Really it was nothing. I'm happy to help."
When he joked about her liking books she could help but laugh a bit as well, "You could say something like that. Books have basically been my life. My mother used to read fairy-tales and other stories to me when I was younger and ever since then I'd been in love with them. Books can lead you to endless possibilities." She then realized how much she was talking and blushed, "Yeah I like books." Gosh she needed to get laid.
Once they got to the gardening section she turned to him again, "Alright here it is. I'll let you browse by yourself. I actually have to check that display over there," she pointed behind him, "real quick. Feel free to get me if you have and questions. She smiled and walked around him to make sure the display was set up to order.
