Friends and family do not believe you write fiction. They truly believe that every word you write is either autobiographical or based on them. I once had a character say that she never wanted to be invited to another children's birthday party, and I never received another children's birthday party invitation ever again.
Often I think bullying - especially in its adult, verbal forms - is the sort of thing you don't realize till the end of the day, and it's a horrible feeling to realize something wasn't just a bland statement, but was actually cruel. But then we're all capable of - of things that are breathtakingly cruel.
Every time I sit down to write, I need to commit to a word count goal, otherwise I waste too much time editing and re-editing my previous work, staring dreamily off into space, pretending that I'm thinking profound, poetic thoughts when really I'm just thinking, 'Look at me being a writer! I'm so happy I'm a writer!'
