Left Buenos Aires at 7pm on a 23 hour bus ride south to San Martin de los Andes. A rather curious fellow (one of six people on the bus, including myself) drank aproximately 35 cups of coffee during the journey, starting at 2am until we arrived at 4pm. He paced back and fourth from his seat to the coffee machince, which we were sitting next to, and filled himself a small cup of black coffee approximately every 20 minutes- sometimes he would leave his cup half full, go back to his seat, then return to finish it within 5-8 minutes. He would sit and sip the black coffee, then return to his assigned seat, and the process would start over again. It was one of the strangest things I've ever seen and felt the need to share this random encounter with you...
