My daughter is an university some 250 miles away. She probably talks to my wife every other day, and Her Boyfriend a couple of times a day (he's about 200 miles from her)
When I explained how I kept in touch with her mother when I was a student in Coventry and she was a student nurse in Birmingham, she does not believe it.
First you send a letter, stating what time you expect to arrive on what day, and where you will meet, in case the phone doesn't work.
then you go to a phone box. There are 8 on the corner, but a queue of 20 people, so you walk to the next corner, and keep walking until you find an empty one. I often got a couple of miles out up into Coundon, before I found one.
Then I'd put a pile of 10ps in front of me, and dial a public phone inside the ground floor of the nurses residence. If you were lucky, someone would answer, take your phone number and go and find her. And then she'd phone back.
If not, you might be waiting for someone to answer, or they'd answer and not have anything to write the number down, and they'd leave you waiting consuming 10ps.
