I-Pod

My father surprised me by buying me an I-Pod, which I had started thinking about getting, but probably would not have actually gotten around to.

I have mixed feelings about it - on one hand, it cuts me off from the rest of the world. I listen to my music and shut out everyone around me. On the other hand, it does make the streets of New York a little bit nicer to walk on.

My final problem - listening to music while I am walking makes me want to dance in the streets but I feel it isn't so tznius. What to do?
