Hmm. maybe start of with something like "What is laughter? " Then write a definition for it and do a story about someone who's never experienced "laughter" and they are trapped in their own little 'bubble'not understanding what all the excitement is all about. I hope this helped.
Some novels are dry and factual. Little is said beyond what is required. Such a technique can be quite effective, as evidenced by the works of Ernest Hemingway and Richard Ford. However, many writers choose to delve into the minds of their narrators and characters, providing a running monologue of what transpires in their heads. This is known as stream of consciousness writing.
