How many ways can you talk to someone far away? Besides making a phone call there’s Skype, google hangouts, LINE, WeChat, and more. And many of these cost nothing if you have the device to do it from and some internet.
It wasn’t always so easy.
In the early 1970s my parents lived in Australia and my grandmother lived in New Zealand. Some years we would phone her on Christmas day. Making an overseas phone call was a Big Event.
During busy periods like Christmas day you would have to phone someone at the telephone company called an operator and book a time for the phone call. When the time came the operator would connect you with the other person.
When we phoned my grandmother we each took a turn to talk but we had to be quick because overseas calls were expensive!
Of course, without science knowledge, ideas and people working hard to turn ideas into inventions we might still rely on letters to talk to our friends and family far away. Perhaps we’d even have to wait for them to arrive by boat still.
