Why is snow not a common experience?
One of the main differences between the Community and our world is that everything is tightly controlled in the Community. The climate is controlled so that no one will be uncomfortable due to weather like rain and snow. Weather is also not needed because they grow food communally and use an irrigation system, and only the area inside the Community is climate controlled. We know that outside the Community there is rain and snow, and there are rivers connecting the Community to the surrounding areas that have weather. It has been so long since there is no snow that no one in the community has seen it.
In the book "The Giver" by Lois Lowry everything in the people's lives is controlled. The people have chosen to let go of things that are not the same. Humans experience emotional and physical changes as seasons come and go. Snow is a part of a winter season. Since seasons evoke responses in humans the community can not have the changes and therefore can not allow seasons and snow. Another issue is that although snow can be fun to play in and beautiful to look at, people can also skin their faces on it, get frostbite, and have extra messes from cleaning up after the wet debri inside. In the community in the Giver those things could not be tolerated.
In the book there is a connotation that starts out explaining the joy of snow, but ends up starting to tell the reader the inconvenience of it in regards to riding a sleigh.
"At first its exhilarating: the speed; the sharp, clear air; but then the snow accumulates on the runners, and you slow down, you have to push hard to keep going."(78)
