I've thought about this before.
A story doesn't have to be like a brown paper package tied up with string - you can leave some loose ends but you have to give a satisfactory close to the main action of the narrative otherwise you're just serving up a slice of life like Andy Warhol's 24 hr. film about a day in the life of a man, including 8 hrs. of him sleeping and all his toileting breaks and meals
that's not art - that's not even documentary - that's security video :)
LOL. Surely, as an author, we don't discuss what a girl of your dream does in the bathroom. Every reader is familiar with digestion and excretion process and would be able to fill in the blanks.
I am talking about the details that are pertinent to the narrative. For example, in one of your previous stories the protagonist was contemplating a thought of whether the beautiful girl he met was a witch. The reader now is prepared to several outcomes: she is indeed a witch, she is not a witch or she is some other weirdo. That is… she behaved in some way different or strange, which made the protagonist’s father suspect her in witchcraft.
Thus, if you would continue the story to the conversation between the protagonist and his father, as a writer you’d have to provide some additional details that would define father’s suspiciousness more clearly and which the protagonist would have to rebuttal. However, if you are lazy you could have just said: “oh, why think so hard? Readers would fill these details of the narrative by themselves.” LOL
ha ha, I get your point :)
