In England they don't want candy, they want money. The small kids with their parents were OK, but they were a small minority. Some years there were no tots. Just older kids begging. And there was a sinister aspect with some. You just knew they would slash your tyres or scratch the paintwork on your car if you didn't pay. The safe thing to do was go out for the night leaving the house in darkness.
The worst thing is, a few more days and it's Guy Fawkes night. For those who don't know, he's the guy (no pun intended) who tried to blow up the houses of parliament some centuries ago. The tradition is to make up a stuffed Guy, and ask for a penny for the Guy. Most kids probably don't know what it is all about, but it's another chance to go pestering people and begging for money. It's not even referred to as Guy Fawkes night any more. It's "bonfire night". So much for dumbing down history. There's also fireworks and bonfires on the night. And fireworks through letter boxes if you don't pay.
Halloween is American. I wish it had not been imported into England. As a return favour, you can have "bonfire night".
Here in France I see small children dressed up and being taken round the shops by their parents. The shops have candy for them. I don't know if they go round houses at night. I lived in town for 2 years and never saw any. Now I live in the country, outside a very small village. No problem!
Don't get me wrong. I like children, but I couldn't eat a whole one (lol).
