Back in the day etc etc.
Mobile phones? heh, weren’t even a glimmer in the developers eye. We would use the public phone network, now departed to let our parents know were were ok. Lots of people had a system too. In those days you could dial the number before putting the money in the slot so you’d dial, let it ring twice and hang up. That means ‘I’m OK’, after that I forget but I dunno, one ring is I’m on my way home, three rings is I’m staying at Martin’s for tea and four rings means you’ve been kidnapped and are currently being rogered by a van load of afghan immigrants.
Aaah, those were the days, I still keep in touch,.
