Why Do You Choose to Work Out in the City?

If i am not staying at home to do work, i will go out to a bunch of different locations to to write on. And the reason why the people at, say, a cafe don't bother me as much is because they're easier to ignore. There's no unity of purpose at a cafe. Also, you're not going to run into the same people over and over. The motion and the change of environment, i find facilitates certain kinds of getting things done.
