Some of it is the frustration of trying to make friends here, which is a bit slow going. I spend too much time alone, whether it is in my room or out in the city, and it makes me feel isolated. If I really want to improve my Spanish, I have to redouble my efforts to meet people and get invited out to places, dinners, parties, etc. I have been trying to make friends on the internet, and I am having a little success but not as much as I would like. I need to force myself go out to more public places (and be more public) this week. In any event, I am leaving Friday on a big trip which will be nice. So far I am planning to hit Oaxaca, San Cristóbal de las Casas, Palenque and Campeche before meeting up with Arnaud in Cancún.
