Chilean Slang and Body Language

I have been wanting to go on this trip to Chile since I was a freshmen, so now that I am finally going on it, I am so beyond excited! I am a little nervous about the flight. I have flown before, but never for more than 4 hours, so this will be new to me. My sister will be traveling to Thailand at the same time, so a bit of me feels sad about my mom being home alone during the holidays, but I know I will send her lots of pictures and bring back some presents! I have a little bit of worries when it comes to not being fluent in Spanish when I think about getting lost and looking for directions or trying to communicate when buying and it being difficult. While I am hoping that does not happen, sometimes worst case scenarios cross my mind. I am not fluent in Spanish but I have taken 5 years of it and also grew up with multiple friends who families spoke Spanish. I feel as though when I am around them I can make out some of what they are saying and expected some of that once arriving in Chile, but after watching these videos, I became very confused! I know that the Spanish we are taught in high school typically teach us pretty formal Spanish that no one really uses, but the fact that there are some words native to Chile like "Po", make it even more confusing for me, and possibly someone pretty fluent in Spanish.
