I am home now. There wasn't much culture shock when I got to Chile so there has been minimal reverse culture shock. It's mostly little things, like the reflex to kiss people on the cheek when i say hello and goodbye and to throw toilet paper in the trash. I'm staying in touch with friends in Chile so hopefully I won't forget Spanish.
I had a fantastic semester and I was really sad to leave, but hopefully in the future I'll have the opportunity to return.
