Side 面向

There are sun side and nightside for a mountain, there are flat and facade for a building. Therefore, we can never observe an object throughly, so does a person. Although our brains are capable of building up three-dimensional things in our heads, it’s undeniable that visually our observation is one-sided. Some people choose to firmly believe what they see, while others choose to suspect whatever they see.However, I think between one side to the other side of a person or an object lies possibilities for our imagination.I do not know if the apple in front of me is sweet or rotten, because I can not know whether there is a wormhole on the back of this apple.
