When I was a kid, people made their own costumes out of old sheets and what not. Chalked up their faces with colored chalk. Filled a long stocking with chalk, crushed it, and went around whacking fellow delinquents and buildings with it. Kids carried a piece of chalk to decorate, i.e., despoil, other kid's outfits. The most we ever bought was a mask. Pumpkins were the real thing. We had a real nasty 'trick' ready, (such as rotten eggs), when we went 'Trick' or 'Treating'. No one would dare to give a kid a sabotaged fruit.
Now I see parents escorting their urchins during certain set times. Late teen thugs still at it. On the odd occasion when they do ask T or T, and you respond Trick, you usually get an inane blank stare.
No imagination; no fun.
