The character in the book named Old Man Warner is set there to show tradition as well as to provide a warning. He said that he had been in the lottery for seventy-seven years, to have survived for seventy-seven years is extremely lucky for him, but he continues to participate because of this town tradition. Though he complains about being in the lottery seventy-seven; he is also the one saying "Come on, come on, everyone." and encouraging people to participate. He doesn't want to get rid of tradition he even calls people who gave up the lottery a "Pack of crazy old fools,". Old Man Warner's place in this story is to represent tradition and sever as a warning that not everyone may be so lucky.
Tone and Theme
In the story imagery is seen all the time like when you can practically feel the "warmth of all summer day;" or you can see that the "flowers were blossoming profusely and the grass was richly green." All of these descriptive terms let you know whats going on and what it's like to be there.
In the story, the lottery there is a lot of repetition. In lines 243 and 259 Tessie says that the drawing "wasn't fair". She continued to say this to try and get the point across to not only her peers but the readers as well. She is saying over and over that it isn't right and a rebellion should start.
The them of this story is that of tradition. No matter how others may see it the presence of tradition is important in a community. This is also seen in the tone because they are calm, this is a regular occurrence in their culture and civilization.
