When I'm #writing #Fiction I often add elements of things that happen in real life into the story.

They are altered to fit the premise and narrative, not accurately described, but the essence taken and replicated. It's usually small things - something annoying, some observation I've made, etc.

I'm sure most writers do this too, but it's often works well to flesh out characters or even to bring in unexpected sub plots. Often these additions can easily be tied into the existing story.
