Today I was in 'San Diego' (that's a neighborhood/street in Santiago) getting bike parts. At one store I bought a set of pedals, and had the following conversation with the 60-something clerk.
Clerk: Where are you from?
Me: Where do you think I'm from?
Clerk: Talk a bit.
Me: I moved to Santiago four years ago with my family. I started...
Me: United States.
Wow! I pass for a Latin American foreigner!
