I don’t know if this is a thing at the moment, but I have noticed in my social media timelines, both in Korean and in English, that people are competitively sharing memories from their childhood that a young person of today would not understand. (What has shocked me most is that children have an entirely different hand gesture for ‘being on the phone’. 🤯)
I naturally have quite a lot to offer on the topic, but perhaps I will choose two for now.
There was a phone number you could dial just to find out what time it was.
A rock star that I was a fan of when I was about 12 lived with his parents, and their home phone number was available from directory enquiries.
