No offense, but the yellow don't typically like the darker shades, if you get my meaning. The Japanese don't even like other shades of yellow! I imagine you're going to be teaching ESL. Do you even speak enough Japanese to be able to interact with these people?

Keep in mind, I'm Asian, and you see how well we get along. I'm really not trying to be a dick, it's just a pleasant by-product of this reality check.
