Imagine a world without names. Nothing has a name, an identity. To communicate to someone, you have to tap on their shoulder, or wave your hand rigorously. The one you hate will not have a name. Just a face. You have to touch him to tell him that you hate him. Expressing your love will always be special and personal. You won't be able to gossip about anyone. Reveal any secret.
Imagine a world without names. All your destinations will be called nowhere. And everywhere. Every fruit will be called a fruit, so will every vegetable. You will never find out what's her favourite flower, or perfume.
Imagine a world without names. All the letters will be addressed to everyone. People will notice people more to distinguish them from the others. That one unique feature, mark, will be the identity. It will not be long or short. Good or bad. It will just be that mark that makes that person special.
Imagine a world without names. You and I will be the same.
