You'll have seen the tee shirts and the mugs and all the other stuff - you know the ones 'Be careful, or I'll put you in my novel' And I know some people do that. Base their characters on people from real life.
I'd be much too scared that someone would recognise themselves and take offence, Or worse. Besides which, my characters tend to arrive with their own personalities - not exactly fully formed, but knowing who they are, and not afraid to tell me about it.
An awful lot of authors also auction the chance to be named for a character in a book - again I'd be a bit nervous. What if the recipient didn't like who I'd chosen to make them? But then, I'm the nervous sort.
Which is not to say that I don't do a little cannibalising, here and there. Clothes - I might borrow them, although usually they are from my own wardrobe, or former wardrobe - or maybe my 'I wish' wardrobe.
But the thing I'm most guilty of 'borrowing.'?
I don't own one, so they are a bit of an unknown quantity. My usual ploy is to decide what my character would drive then go on a hunt to find one in the metal, as it were. Supermarket car parks are very good for this. Not sure what the CCTV makes of it, but the cops have not come knocking on the door yet. I got a bit stymied when I wanted a Bentley. For that I had to go to the posh show rooms and prowl, while looking as if I could really afford one. I got a very nice Porche out of that trip too, so it was time well spent.
So - I won't put you in my book. But I might steal your car.
