Re phones, I was born in 1949 and I can’t remember not having a phone in the house. And my parents certainly weren’t well off - permanently skint was more like it.
I can still remember the code at the house from when I was 6 to 9 - UPL for ‘Uplands’. Can’t remember the actual number though.
But as was common then, the phone was used only when absolutely necessary - certainly no long chats. Phones were often in the hall anyway, so in pre central heating days you wouldn’t linger in the freezing cold.
Dh’s father used to make him and his brothers pay for any call they made - probably 3d at the time.
