The World Needs to Hear the Conversation I Just Had

In my kitchen, with my host mom and sister (stefie):

Me: ¨Mañana unas amigas van a visitar despues de las clases para estudiar la Biblia. Muy tranquila. ¿Está bien?
Tomorrow some girlfriends are going to visit after class to study the Bible. Really calm-like. Is that okay?

Stefie: ¨Viernes depués de las clases voy a charlar y farrear con unas amigas. Muy tranquila también. ¿Está bien?
Friday after class I´m going to get drunk and do some wild partying with some girlfriends. It´ll be really calm too. Is that okay?

I honestly think that this might be the funniest thing that´s ever happened in my life.
