But trying to hold a conversation with Snooki is a little like getting down on your hands and knees with a child. You have to come down to her level, and sometimes you almost think you need to bribe her with a piece of candy to coax her to be more responsive. She is really only responsive to her own immediate needs and desires. She is not self-centered, but she is used to acting out and getting away with it.

She simply isn’t capable of serious introspection. She told me she has read only two books in her life, “Twilight” and “Dear John.” When we were in the kitchen at her dad’s house, I asked Snooki if she were inspired by any movie actresses.
…
“Movies?” she said thickly. “I really liked Brittany Murphy. Yeah. I looked up to her. She had a dorky personality, like me. It was sad that she died.”
“You have a dorky personality?” I asked her.
“Yeaahh, don’t you think,” she drawled, playing with her hair. “I’m a nut job. And I don’t care.”
