Teaching English!
Such a challenge! Unfortunately, I won't manage to realize myself as a teacher here. The school bursar, who's taking care of the volunteers, hasn't taken care of anything at all. I had 12 hours of class in 2 weeks, with the other volunteer (from Czech Republic) teaching to the same class at the same time. There were school holidays taken place while I came to the village, and English teachers in this area are more than decent. My presence here is therefore useless.
I had just enough time to get bored before I decided to move asap, at least I had some free time to read books, rest, and enjoy the house by the beach that they let at the volunteers' full disposal!
