Outside the UK, New Zealand, probably Australia, and maybe some other Commonwealth countries, nobody else will know about Guy Fawkes Day. That on the 5th November, we commemorate a plot to blow up Parliament back in what, the 1700s? (WTF? I can see everybody else saying)
When I was a child, every household had their own little display in their back yards. I liked the fireworks but I was also terrified of them. I wouldn't go outside till it was all over, but watched through the window, my stomach clenched in a knot till I knew my father and brothers had made it through safely without blowing themselves up. I was even nervous with sparklers.
And those few weeks beforehand when you could buy them in any dairy, and there were always groups of boys standing round after school, ready to throw bangers at anyone walking past.
Now, in NZ, most cities have free public displays. @sift666 and I met on Guy Fawkes night, many years ago, so we always appreciate the city putting on free fireworks for our anniversary.
But you can still buy fireworks for your own displays, though only for about a week beforehand now. Sometimes we can see local displays of skyrockets later that night, or on the nearest weekend, and then some usually get saved for New Years. But overall, it's much less than it used to be.
