The Phone Call

Some people just don’t know how to talk on the phone. I called up my friend the other day to tell him something. I didn’t get a word in, he started to ramble on for three minutes straight. Then he said “OK, I got to go.” I said wait a minute, I didn’t tell you the reason I called.
Another friend called me up and said “What’s up?” Then he didn’t say a word. I had nothing to say. Then there was complete silence on the phone. Finally I said I got to go.
Whats the point of calling somebody if you got nothing to say.
