Children get very excited, they have fun because they dress up as their favorite characters and because in a certain way adults also have fun and behave like children, in the sense that some also dress up and are kind when handing out candy, it is a holiday to have fun and stop being "serious and boring" for a day. In public schools here they do not celebrate Halloween, coincidentally today they also celebrate "criolla music" so they give priority to this holiday. How great your daughter's school, regarding candy, our daughters have something in common, in the end they do not eat all the candy, and it can last up to a month on the table.
