Catalogues.
Leaving babies outside shops in prams.
As a PP mentioned, sexual harassment being treated as pretty much a rite of passage when you entered the workplace.
Spaghetti bolognese and yoghurt being exotic in the 70s.
Taking sandwiches and a flask on days out, because even greasy spoons were a treat.
Reins on toddlers being absolutely standard.
Buses with a conductor coming round to take your money with a leather pouch for the money. If you did regular journies and got to know them, you might be given the end of the rolls of tickets to take home and play with.
Your grandmother saving up margarine tubs and toilet roll tubes for you to play with, and hours of fun emptying kitchen cupboards and using pans and wooden spoons as drums. (I know some people probably still do this to be fair, just there wasn't quite the proliferation of toys that there is now, and if your family was on a tight budget, they were few and far between).
A pound a week pocket money being considered extravagant.
