How do you pass time when traveling?

I'm sitting in Argentina international airport waiting to check in, bored out of my mind.

Kinda wish I had my Ds or a book with me, my friends are sitting beside me buried in a book, im jelly, there are book stores here, I saw a game of thrones book and jumped at it but alas, its in Spanish

Only an hour left before I can check in, then another 3 hours of waiting around, I hope there are more book shops with English books or somewhere to buy new headphones, my last pair just randomly stopped working, which is a shame

We kinda had go come straight to the airport as its election day in Argentina and EVERYTHING shuts down and we had to check out

Anyways, what do you guys/gals do to kill time in your travels??

I really need to read more I think
