1. Showing vs Telling Warm up exercise:
Convert the following ‘telling’ narration into ‘showing’, i.e. into dramatization with concrete spoken dialogue as opposed to summary. Add more details (sounds, etc), use speech marks, indents and keep it in the PAST TENSE:
She answered the phone and gave her name. She said she did not take cold calls and that she regarded them as an invasion of privacy. She added that she was especially not interested in double-glazing.

2. Specificity
Descriptive writing, or the art of painting a picture in your reader's mind, is one of the most powerful techniques to master, whether you are writing fiction or nonfiction. The key to making it work – and to making your prose more powerful – is specificity.

3. Specific Words
Usually when people read nonfiction story, they want to know they are getting as close as possible to a firsthand account of events that really occurred. They want to feel as though they are hearing the story from someone who was there, and a genuine eyewitness can give specific details of what happened. Although people know fiction is, well, fictional, good fiction should nonetheless have the have the ring of authenticity to it. Again, the way you convey that authenticity is by descriptive writing that includes specific details someone who was actually present would know. So what could we do with our vague first sentence?

4. Specificity “A man walks into a bar”.
Make this a better sentence with more specificity.
Characterisation, intent, POV, setting, strong verbs that indicate characterisation: why are they there? Who are they meeting if anyone, psychological state, physical attributes….
draw the reader into the world of the story by being there for them.
Now add more specific detail to see what kind of story might emerge.
Remember: Show Don’t Tell.
