I knew about 5-digit dialing, but never knew people used to dial only 4 digits. That's pretty neat, and probably made life with a rotary phone much easier than people my age realize.

I'm a younger millennial so it was no big deal to grab the landline and dial 1+10 digits to call my girlfriend long distance in 2009. On a rotary phone, it'd probably have taken til supper just to dial lol

I did find a rotary phone in a box at my great grandmother's house once and played with it because it was fascinating to me. Then I dialed a random 800 number on it and remarked that it was kinda amazing that so many people bought things over the telephone in the day.
