My classroom had one of the giant chalk boards that you rolled round, no Interactive white boards or plastic white wipe-clean numbers.
We didn't even have that, our teachers had a blackboard and easel, which they cleaned with a brick shaped board cleaner. One teacher used to lob it at the boys when they misbehaved. Everyone thought it quite funny, nowadays the poor teacher would be hauled in front of a court for child abuse.
Can you still remember your old telephone number?
Altrincham 1072. It must have been about 1946, we had a shop so the telephone company had to ask my mother's permission to change our line into a party line. I think she got a reduced rent for agreeing. Next one when we moved into our first house in 1954 was Ringway 3050. Funny, I can't remember the telephone number we had 2000-2005 in our last house

And my Dad sending me to the shop to get his tobacco for him (I was about 10 years old at the time - it wouldn't work now).
I used to get them from the off-licence when I was about 10 (for my parents, I don't and never have smoked). Imagine a 10 year old going into an off-licence where drink was available and buying cigarettes and no-one thinking it was anything but normal.
Top of the list of things I wish we'd had when I was young, has to be a mobile phone. Imagine being able to ring or receive a call from, a boyfriend without your parents listening in on an extension. Or getting a text rather than a letter which your mother had already opened when you got home from school/work. When I'm out and about the people I envy most are the young, not because of their youth necessarily, but all the opportunities they have today for education and travel.
