I moved to Cork city in August of 2009 because I liked the place. I'd been there most recently the previous December for a TEFL class, and felt good visiting.
I had grown to dislike Kilkenny, and while I had some friends there I was disatisfied. Local kids had been taunting me with filthy language for a couple of years, and the landlord in the place where I'd lived for years was harrassing me regularly.
And I liked Cork. So when I returned from a vacation in Romania, I went to Cork with a backpack, and got a place to stay in a hostel.
