You often hear you should write about what you know. Does this apply to writing about who you know? This is what can go wrong when you write about who you know: In this week's episode of Gossip Girl, Dan Humphrey announces the publication of his book to his inner circle of Manhattan's young elite. The book showcases the lives of his close friends and loved ones. At first, Dan's friends and family are amused with the idea of being in the book, but as they read through it, most get pissed over how they're portrayed. Serena, Dan's ex-gf, is upset at being shown as a self-centered party girl. Rufus, Dan's father, doesn't like being labeled as a washed up musician and trophy husband. Blair, who is engaged to the suspicious Prince Louis, freaks out at the suggestion she and Dan had hooked up hooked up. (Blair should've figured out Dan wasn't trying to cut her down when he suggested they'd gotten together. It was wishful thinking on his part, and MINE too.)
At the end of the episode, Dan's inner circle is gone and he is all alone. Poor Dan...he didn't even want his secret book to be made public. On the bright side, no one threatened to sue him.
The outside universe provides a wealth of inspiration to writers, unless one is an absolute hermit who never ever leaves their home and never ever communicates with anybody aside from the voices in their head. So I wouldn't be surprised if some writers may sometimes get ideas for some aspects of their fictional characters from consciously or subconsciously picking up vibes from others, and they can do it without pulling a Dan.
My take: If a real-life person inspires a character to be portrayed in a flattering way, the writer should still convey this is a made-up character. Now if a real-life person inspires a character who's all sorts of gross, the writer should proceed with some caution when revealing this character who is supposed to be (REMINDER!!) fictional.
