Grinder,
This is normal. This is abnormal.
I read in a book somewhere (Carole Blake’s I think) that, once you ‘come out’ as a writer, your family and friends immediately divide into two camps: those who are miffed because they think they are not in your book and those who are miffed because they think they are.
The trick is to amalgamate characteristics into your characters so that real people are not quite sure if it’s them or not – then they can put their own interpretation on whatever you write. Hopefully this will keep them happy! And off your back while you get on with your writing.
Good luck,
Dee.
