The lottery is a communities tradition that has been going on many years. They sacrifice someone by pelting them to death with stones. The elderly people in the village despise the idea of not having a lottery because it has been a tradition for many years, ""Nothing but trouble in that," Old Man Warner said stoutly. "Pack of young fools."
An example of foreshadowing in "The Lottery" is when the children are gathering a large pile of rocks. The line in the text says,"--eventually made a great pile of stones in one corner of the square and guarded it against the raids of the other boys." This is foreshadowing that something is going to happen with the pile of stones
At the beginning the setting was happy and was described as sunny, green fields, "The morning of June 27th was clear and sunny, with the fresh warmth of a full-summer day; the flowers were blossoming profusely and the grass was richly green." As the story goes on the mood gets darker as we learn what the lottery really is.
