Clase Particular

It's the second week with Beatriz. I'm having conversation class with her in English. Jerica recommended me to her. I'm charging her 15€ and what happens is I let her talk about her technical work and I ask follow up questions. I do my best to correct her when needed but she has a really good level of English so it's hard to give feedback. Even though this is a conversation class it takes a lot of brain power on my side to understand the technical concepts. Well it's an easy way to make some extra cash but if I have to buy drinks every time it does take away from the profits.
