I've only been abroad one time, and there were little gecko/lizard things everywhere, climbing up walls and scurrying across roads, and nobody cared. I was constantly fascinated but to the locals they're just kinda there.
Bonus question to anyone who visited the UK - was there anything that fascinated you but I'd be taking for granted?
When I was a kid we hosted two Trinidadians as part of an exchange in the Autumn and they'd never seen the leaves falling - they were worried that all the trees were dying off. This isn't a "stupid foreigner" gag, it was probably just the thing that shocked them the most. They loved the trains and the narrowboats.
