Water and rocks
Water is freer than rocks. It lets anyone in without being hurt. A rock must be worn down to dust before anything can enter it, but the water welcomes a rock into its fold like it’s nothing. Water evaporates into patient clouds: it has no borders. Rocks are mined for and coveted and blood is spilt over them. They hide in pockets yet you can’t even eat them. Water is that thing humans never think of or always think of, depending on whether it is plentiful. People who have lots of water want rocks and people with rocks need water. In the heat of your hand a chunk of ice will change, but a rock thrown will never be recovered.
