There are two sides to this topic. Firstly, old people can become very scared at this time of year, because they may live on their own and be afraid of not answering the door. My mother moved to a sheltered home last year, and she is glad she does not have to endure another trick, or treat. On the other hand I love it, and give out all the goodies I can, but later on in the night it can be a problem, as that is when the teenagers come knocking, and I feel a little intimidated by this. They arrive after 9oclock at the door, and in big gangs. I think maybe a time limit on when it should end would be safer and not so frightening for people who live alone. We must remember them, as they are vunerable. It is easy to sit back when you have a house full of people and moan about the ones who complain, as they may have good reason to do this. Not every area is safe, and can become worse this time of year.
