Fear of the Foreign.
I love summer because so many people travel and a few more bricks in the wall are taken down.
Every time I fly over the ocean, I try to pinpoint the exact spot over the Atlantic where I become a foreigner.
I've lived outside of my home culture to the point that the wall for me is rubble. That's a good thing. I am also a francophile. :~)
As far as writing for kids goes, I think they are starving for stories outside of their home cultures. My own stories are Jason Bourne for kids (boys, in particular). Fun. Fast. But quelque chose de different.
