Amanda Knox, who was acquitted of killing her roommate, Meredith Kercher, while studying abroad in Italy in 2007, drew social media's attention when she responded to a New York college student's essay complaining about her semester abroad.

"Girl, what are you talking about? Studying abroad is awesome!" Knox tweeted in response to the "Insider" op-ed titled, "I'm an NYU student who studied abroad in Florence. I hated every aspect of my semester abroad."

The author of the essay, a New York University student named Stacia Datskovska, said she "grew to despise the sights, hated the people, and couldn't wait to get back home to my campus in New York" after her trip to Florence.

She listed her roommates' differing schedules and values; the locals' hostile attitudes; and the continuation of "life back in New York that went on" without her as some of the reasons she disliked her study abroad experience.
