Fortunately, having been around for quite a few decades, I’ve had a great many experiences - mainly good, though not exclusively! So I think I can write about a wide range of incidents.
Where I don’t have direct experience, I’ve chatted with so many other people (as counselling clients, friends, members of groups I’ve been involved in and other acquaintances) that I know who to speak to and, of course, there is the Internet these days.
I hope, therefore, that my novels come across as “authentic” - it’s a pet hate of mine when an author describes something that simply couldn’t happen - or not in the way described. I find it destroys their credibility. I do hope I don’t fall into that trap - though I accept that we all make mistakes from time to time.
My début novel, Summer Dreams, was inspired by a real event and most of the incidents described (or something very similar) have happened - but the story and is a work of fiction as are the main characters. If you recognise some of the locations - that wouldn’t be surprising.
