I've got a real sense of three-dimensional geometry. I can look at a flat piece of fabric and know that if I put a slit in it and make some fabric travel around a square then when you lift it up it will drape in a certain way and I can feel how that will happen.
Americans are cool if you show just a chink of vulnerability they respond so much. They'll pat you on the arm and say 'Hey kid you're all right.' Brits will respond but they are much more cynical.
