The English Language
I went in to England expecting to learn a dialect of English. Instead, when it came to the areas near small shops and takeaway restaurants, it ended up being more akin to learning the signals given by primates at the zoo. I learned what a high piercing language-less wail meant in comparison to the lower grunting. I began to learn what the different grunts and series of grunt meant – some were sexual, some referred to drugs, and some were just a reaction to new people entering the environment (the latter is higher pitched and more urgent sounding).
