intriguing

It's not usual that I'm afraid to talk to someone. I won't talk to people that I think dislike me, but that's just out of a desire to avoid conflict. But for some reason I'm afraid to talk to her. She's quiet, intelligent, and above all intriguing. I'm afraid to talk to her lest I appear dull, or I find out she disapproves of my ways--how she could disapprove! She doesn't seem sanctimonious or arrogant. She just seems, well, pure. She wouldn't want to disapprove because she was judging us, it would be like me disapproving of dirt or something. I don't know.

Does she know she's intriguing? She doesn't seem like it. It's almost like it would ruin it if I told her.
