Has this happened to you? After a long time you receive a phone call from an individual who has long forgotten you, might be due some circumstances or was too busy or just wanted to. You would never know!!
The first reaction of your would be wow cool,how are things? and nice to hear etc. But imagine at the end after all hi & hello’s you realize it was because he /she wanted something from you, hence was the call. After you supplied the information the talk was over abruptly. Strange enough!
A connection that disconnects after the receiver is down.
