"Bagels – they're the best thing ever! Americans just love variety; there's so much choice, it's overwhelming," the actress/student, 20, tells Parade. "But I love trying the blueberry and raisin and cinnamon bagels. Luckily, I exercise a lot."
It's not just bagels the British star, now a sophomore at Brown University, flips for since hitting this side of the pond. She finds mundane things more thrilling than the average person might after having spent years on film sets with people "telling me what to do."
"Someone needs to know where you are every second of the day," the Harry Potter series star says of filming. "Here, no one tells me what time I can have lunch, when I can go to the bathroom."
"It's incredibly empowering and liberating," she adds. "My friends think I'm crazy because I get so much joy out of really simple pleasures like staying up late talking or deciding to go for a walk," she says.
Another perk of being on campus? Anonymity.
"I'm used to people being intrusive and gossipy, but I can be anonymous," Watson says. "My best friend at Brown has never seen a Harry Potter movie or read the books. And one guy I dated didn't know anything about the films, much less that I was one of the stars, which I found hilarious."
Her latest movie, Harry Potter and the Deathly Hallows, Part I opens Nov. 19.
