Phone boxes were cool man. You can't play 'how many people can we fit into a mobile phone' can you?
We never even had a phone at home when I was a kid (not completely uncommon in the 70's). Everything was done in the phone box down the road. Ridiculously I can still remember the number. Every call was free. You either repeatedly hit the silver bits on top, or, if that failed, ring the operator and say you've lost your money and they'd put you through for free, usually wandering off forgetting they'd done it so you talked forever. And if they did cut you off, your friend would ring you back. Which is how I remember the number still. It was course, you missed proper MDMA.
Must be shit being young.
