It's the small things, like writing the date on class notes 22.4.2015 or saying I live half a kilometer up Irarrázaval. The ways in which you've changed but don't really know when exactly it happened; they just kind of sneak up on you. Elbowing my way into a metro car (forget Midwestern nice, if you're making it into that car you gotta squish), strategically placing myself in the metro car depending on how many stops I have to go to avoid having to wade through 20 people to get out of the door before it closes at my stop. Keeping spare 100 peso coins in my back pocket (damn no front pocket in womens' jeans) to give to street performers or musicians on the metro. Knowing to hold up the number of fingers you want for thousand pesos you want charged to your Bip - holding up 3 fingers for 3000 pesos - because the card rechargers can't hear very well through the glass. After three months abroad, two of them in Chile, a lot of things have snuck up on me. And it's nice to know you've learned something, especially if they're the small things.
