Many of the students at my English school are high school students. I often ask them about their classes, what they're studying, what they enjoy, what they think is boring.
The other day, I found out that every eleventh grader in Vietnam studies "Army". The curriculum includes military strategies & war tactics, as well as how to use an AK-47. Yep. They all know how to use an AK-47. Really. Every man & woman in Vietnam over the age of 16 knows how to use an AK-47.
Why, I asked. In case they're invaded again, they said. Now that's being prepared!
