Alexander Graham Bell, the inventor, suggested that people     8     (say) “Ahoy”, but finally “Hello” went out, the greeting used in everyday face-to-face communications now.

Try to be respectful no matter     9    you communicate with. Just keep    10    mind that politeness never goes out of fashion.
