I feel it in the city. People keep to themselves. People just go about their day. Not much socialization or anything. It's 'Go to work, come home' or 'Go to school, come home' it typically feels.

Even I am guilty of going into Boston and just putting headphones on and just walking around without interaction.

Some chat. I would wear my headphones less if I was less concerned about random people walking up to me to panhandle or something. The headphones wards them..... most of the time. Not all.
