So I got a call a couple days ago from the assistant dean of admissions for the Flora Thorntan School of Music at USC , personally calling me to talk about financial aid and my admission to USC . Unfortunately I had already commited to Cal State Long Beach . Still and all , it was really cool to have him call me personally and talk to me .
