Memories of a non-digital era

I was helping my dad get rid of old stuff in the attic when we came across an old computer. It was so big and old-fashioned! He told me it used to belong to his older brother when he was a boy. When he left home, he gave Dad the computer to write essays for his homework. Dad explained that that was about all he could do on it! The internet didn’t exist when he was younger, so he couldn’t spend time chatting online or posting messages on social media. Imagine!

When he wanted to chat to a friend he used the house phone because mobile phones weren’t common. Only rich businessmen had them and they were large and heavy. So when Dad made plans to meet a friend, he had to hope they remembered where and when to meet on the day because they couldn’t contact each other. If his friend was late, he had to wait. It happened a lot! And while he was waiting, he didn’t play games on his phone because he didn’t have one! How boring!

Dad said my uncle used to live in Australia, and the only time he spoke to his brother was once a year because telephone calls were so expensive. Instead, they wrote letters to each other. Now, you can video call anyone in the world for free! Dad said he hadn’t realized how much life has changed because of technology until he came across all his old stuff!.
