The proper use of the phone

• Do not call before 9: 00 meal or after 21: 00 hours
• If we call you, answer "Hello?"
• If you call, tell who you are as soon as a voice answers you.
• Be brief: the telephone is a medium of communication, no conversation.
• If you are calling in the distance, it can be expensive: so don't waste time in unnecessary politeness.

All this seems weird to you? Normal: It was in 1969, 40 years ago. For a great Moment of emotion, run the video of a report of the TSR of 1969.
