Random walks

Have you ever been to undeveloped countries?
Or you live there? Anyway, what I'd like to tell today, is nothing but a visible scene you can see almost everyday in such countries. What? Well, just take a look at the streets; occupied by people who seem to be in rush. Think about it please. Thousands of people are just moving (it is mostly like a marathon) bumping and hiting eachother. But are they really in rush? Is someone waiting for them? Or is a job delayed? Not sure but most of these are just random walks for nothing. They just want to show themselves in this style.
Developed countries, on the other hand, do not suffer from such a disease (if I can call it this way). It seems to be no rush there or at least poeple do not pretend. Here, almost everything goes well without such sorts of shows...
