Time indeed has changed

Peoples attitudes have undergone a sea of change in the last decade. I distinctly remember that people used to be more friendlier towards each other, even towards strangers. When someone ran across someone or saw them across the store, they used to give some sort of greeting. Maybe a hello/hi or just a nod of head. Even strangers sometimes seemed to be courteous. But these days, no one has the time for simple greetings and everyone seems like total strangers. Times seems to have changed alot it seems. People have seemed to have lost all their grace and manners with the passage of time. Everyone seems to be in such a rush these days that they simply do not have the time for simple greetings. Everyone seems so withdrawn into their own shell. No one wants to make eye contact with the other person on the bus, taxi, etc.
