According to Wikipedia, this is what a Slice of Life Story is:
A slice of life story is a category for a story that portrays a “cut-out” sequence of events in a character’s life. It may or may not contain any real plot, and often has no exposition, action, conflict, or denouement, with an open ending. It usually tries to depict the every-day life of ordinary people.
I am planning to join the Slice of Life writing challenge this year! 31 days of writing!!
