I remember there were wall-phones in every room. I bet now dorms don’t bother with that and expect students to have cell phones. And I had a “calling card” (remember those? They were like a portable long-distance plan where you could call from any phone that did long distance, and it would be charged to you) so I could call my parents. (I think once or twice, when I didn’t have the card handy and it was an emergency, I called collect — probably something else today’s kids don’t know about — but I understood that was an emergency thing because of the expense.
I was insane enough to order my very own single-party line for my dorm room, which cost a fair sum of cash during an era when minimum wage, about the most a student could reasonably expect in those days, was a buck-thirty. (And yes, I remember the number.)
