"When we pick up the phone, we say '#Hello' But what is 'Hello'? It is not a greeting but rather the name of a person. It is '#Margaret Hello,' the fiancée of the #telephone inventor '#Graham #Bell.' It was the first word he said in the initial test of his #invention, and it has been used since then as the opening of any #phone call worldwide." #historyfacts #historicalfacts #everyonehighlights #reelsviralシ
