I was talking to a coworker about these new phishing attacks that send your name and address and sometimes a picture of your house, and I was saying how creepy it is, and they told me that phonebooks were delivered to everyone and used to have like literally everyone in a city listed by last name with their phone number and address. Is that for real?
You also need to keep in mind that there were not nearly as many phone numbers back then. While today a family of 4 might have a cell phone for each person (especially by the time the kids are teenagers), in the 20th century most families just had one number for the whole household (and the earlier you go there might have even been just one actual phone in the house).
