Primary school in the 1960s:
School lunches: no choice, not being allowed to leave anything on your plate, eating off proper china plates and drinking out of proper glasses.
Outdoor loos with cracked wooden seats, chains to pull and broken glass in the windows. Having to ask for loo paper when you went to the loo (it was strictly rationed and we weren't allowed paper if we were just having a wee).
Having to hold up your handkerchief in the air if you sneezed - to prove that you had one.
Having to spend all of 'playtime' outside all year round. When it rained, we huddled in 'the shed' which had a roof, but only one wall.
Being sent out with my best friend and a piece of chalk each on Friday afternoons, to draw a netball court on the playground before we played.
And, as others have said, milk, and PE in vest and knickers.
