I didn't have a mobile phone until about 1998 ( I was 28 then and had resisted getting one for quite a while as didn't see the point)
Before smart phones existed I used to buy a newspaper every morning to read on the train. Would do the daily crossword and sudoku puzzle at lunchtime. There would be a few of us all trying to solve the same ones so we'd all be helping each other.
I'd use the landline at work to phone my friends or to let my mum and eventually husband know that I was leaving the office and which train I'd be on. We used to have an honesty box come round once a week so we could contribute towards personal phone calls.
Phone box were used to call and ask parents/husband for lifts home from places. If the trains were messed up there would be a massive queue to use the pay phones.
I always had a book to read on the journey home.
Evenings would be spent cooking the dinner and then a couple of hours of watching TV. DH and I joined a gym because he hated watching Eastenders etc and suggested we should get out of the house and do something else instead.
One thing I loved was going to friends for a TV evening. If there was a special double episode of Friends or a special event being televised we would get food and wine and all get together to watch it.
We made much more effort to see people before smart phones/Facebook came along.
Booking holidays was completely different obviously. You just had to trust that the hotel you had booked would be ok as you would have no access to reviews.
Booking weekends away in the Uk Involved phoning the tourist information office for the town you wanted to visit to ask them to post you a list of hotels , guest houses/ bed and breakfasts. You then phoned the one you liked the sound of from the very short description. Sometimes you had to post a cheque to them to secure your booking.
Feeling all nostalgic for simpler times now!
