A shed is a small building that people use to store things like tools, bicycles, or lawn equipment. It's kind of like having a special closet or cupboard outside of your house. Some sheds are made out of wood or metal and have a door that you can lock to keep your things safe. You might see sheds in people's backyards or in parks. They are helpful for keeping things organized and clean, and they can also protect your belongings from rain, snow, and other weather.
