In my free (and sometimes, not so free) time, I enjoy reading all kinds of books – from classics, to fiction, to (some) poetry (think Rumi). On a pleasant day (but wait, you live in Chicago!) you would probably find me by the lake, or waterfront of some sort. Trying new cafés and restaurants is always a treat.
