Try to picture what used to happen earlier in the days when people had to depend on the good ol’ postal system. During those days, a person had to wait for one or two days for a letter to get across to a person who lived in the same state itself.
The second person in turn would take one or two days to respond and this letter would take on or two days to get back to the first person.
So in effect, a single correspondence would stretch over a week. But now it’s a total y different story. The time taken for the first letter and the response has been brought to an amazing 2 minutes!
Waiting may make the heart grow fonder but e-mail makes two people get close faster!
