Flannery O'connor said this quote
“ Fiction operates through the senses, and I think one reason that people find it so difficult to write stories is that they forget how much time and patience is required to convince through the senses. No reader who doesn't actually experience, who isn't made to feel, the story is going to believe anything the fiction writer merely tells him. The first and most obvious characteristic of fiction is that it deals with reality through what can be seen, heard, smelt, tasted, and touched. ”
