If you are to use Alexander Graham Bell’s product, which is to say the blower, you should, in all courtesy, use it as he would have wished; and Dr Bell insisted that all phone calls should begin with the words ‘Ahoy, ahoy’. Nobody knows why he insisted this – he had no connection to the navy – but insist he did and started every phone call that way. Nobody else did, and it was at the suggestion of his great rival Edison that people took to saying ‘Hello’. This seems unfair.
