Tradition - well, maybe. But times have changed. I may have posted about 'old times' before, but when I was small, Guy Fawkes Night was a real treat. We always went down the road to a neighbour's house, and took our homemade mince pies plus a half-crown box of fireworks. All the other children did the same, and the dad, Mr Jones, let off the various types himself:-
Catherine wheels (pretty but not noisy)
Roman candles (three softish bangs with three different colours) Golden rain (pretty and quiet)
About three small rockets (whoosh rather than bang)
and of course my favourite: sparklers, which we waved around making patterns.
Our stuffed Guy burned merrily on top of the bonfire.
Now none of this was particularly noisy,and lasted about twenty minutes. No appalling 'explosions' like bombs.
If things were exactly the same now, I think it would be better.
