modern conveniences
Paddy didn't blink one time at modern devices. Yeah, he was annoyed about the casino machines in his pub. Otherwise, he didn't even blink at cars, electricity, the cell phone, the dirt bike. I couldn't tell what time he was actually from, because the US and Australia may not coincide, but i was guessing late 1800's.
The only person who seemed to react, somewhat, was the world war one kid. Charlie? Can't think of name. He was touching the lamp. He was surprised there were two world wars. He looked up when a commercial plane flew overhead. Yeah, they had airplanes in WWI, but not the big silver/white planes we have now.
If noisy giant metal things were all around, and I'd never seen a car before, I would be freaked out. Not sure I would just jump in one.
