Why do the pictures of classmates around us all use other people's pictures as their own pictures? Why are their signatures and conversations so meaningful?

Just as there are no two identical leaves in the world, there are no identical people in this world. Everyone has his own personality and style. There are cute, mature, sexy, straightforward, frank and implicit. There are many kinds. It is because of the differences between people that the world is so wonderful. So don't envy others, maybe others are envious of you. Each has its own wonderful things.
