Treat or Trick?

On Wednesday night,
when I was walking along the Rua Praia Grande,
was stopped by few kids,
who were wearing the Halloween costume,
they handed me a pack of unknown item,
I was kind of shocked by the gesture,
anyway,
to be polite,
got the pack from their hands,
and realised that it was Halloween!

Forgot to say thank you though,
when I continue my walking to the destination,
I was thinking,
in a city,
for the kids,
it is fun to have the halloween party,
but,
it is safer not to eat the candies from the strangers!
