Marnie: (on her college, DeSales University) DeSales is the only one that was not a conservatory. I was looking at BFAs, but when I went and visited all the colleges, I felt most at home and comfortable at DeSales, because it's a very well-rounded school. You can do theater, you can perform and do all that, but you can also have friends and hobbies outside of it.
