Take into account that I’m English, from very near London, and born in 1975.
In London, the decade started with lots of bomb threats still in London, and a fair few real bombs. I worked in a large shopping centre near London at the very beginning of the decade (I started work younger than usual) and it got completely cleared out a couple of times due to bomb threats. Later, I worked at Victoria station and we could count on a few hours’ free pay once a month or so due to bomb threats.
At the end of the decade there was the Good Friday Agreement and then the Omagh bombing, and it almost all seemed to stop.
Drugs were mainly LSD, e, speed and dope. Cocaine was more for the rich and heroine was more for the desparate.
Music was grunge and indie bands like Pulp, Blur and, sadly, Oasis. Raves were what you did unless you were boring or old.
Mobile phones gradually decreased in size and increased in popularity over the course of the decade. Most people had Nokias - that Nokia ringtone is the sound of the nineties.
The internet was so new that, on my MA in 1998, I had to write my own protocol for how to cite websites.
Most people didn’t have the internet at home, even at the end of the decade. It was more common by then, but I would still get asked to do things on that internet thing by people who didn’t have access themselves.
Living away from my friends, to call them I would queue up to get to a phonebox, use a phonecard to call them, then have them call me back. When abroad I did the same or used friends’ phones, and I wrote a lot of letters. Personal letters were still fairly common if you were in another country for a while.
Fashions were similar to now, because the nineties is now long ago enough to be retro. I can actually still wear a skirt that I wore when I was 16, because it is fashionable again and I still fit it.
