Did you write this about our childhood?

I was speaking on the phone with my sister tonight. She sometimes does graphic design, so I asked her if she could make a polished version of the Mission: Dawn insignia that I designed.

She said she could look at it when she has time, and asked me to email her my design. Well, I've already put a sketch up on the blog I set up for my novel-in-progress, so instead of emailing her a copy, I told her to go online and get it from there. She went to look for it while we were on the phone, and on her way to the relevant page she happened upon a scene I wrote recently called Bright of Sun. She read the first few lines:

"Knock on the door."
"You knock - you're older than me."
"I'm older than you so obey me."
"No! Just because you're older doesn't mean you always tell me what to do!"

When she read this, she asked me if this was supposed to be about me and her. She said it sounded like something I would have said to her!

That's funny. I wasn't consciously drawing on my own childhood when I wrote that dialog. But, come to think of it, that scene just came to me, just popped into my head, one day while I was driving home from work. I really liked that scene too; I liked the bickering between Nesta and Kitoyo. So, maybe my subconscious mind really was drawing on my own childhood when it delivered that scene to me.
