Starbucks Mejicanos Unidos

Today I ran into Guillermo, a friend from college. In Chicago.
So I was hanging out at a (wait, don't judge just yet) Starbucks on Michigan Avenue... I was there only for the free internet, big windows and Christmas environment... but anyway, I was there minding my very own French business when I looked up and there he was, holding a million bags from Crate & Barrel, The Apple Store and Louis Vuitton. He made a weird face, which I bet was the same one I was making and came over to say hi... followed by his girlfriend from college, Sonia, whom I also knew.
Now, we weren't über best friends back in the good old days; it was more of a hi-on-the-hallways-bye-at-the-end-of-class kind of friendship but still, we are in Chicago, people. We are thousands of miles and many Fahrenheit degrees far away from each other... what are the odds?!
Now I've officially ran into three people from Mexico while in here. I wonder why when I was home (a considerably smaller city than this one) I never ran into my dad when I skipped school and used to go for tacos at 11am just a few blocks from his work. Oh, the absurdity.
Also, they said I looked american...

Wait, what?
