I am a teacher, and I’ve taught many types of students, but my most recent job, and perhaps the one I loved most, was as an ESOL (English for Speakers of Other Languages) teacher for adult students. I specifically worked with advanced-level English learners, meaning that most of them were professionals in their own countries and were extremely intelligent people.
I learned just as much from them as they did from me. Most importantly, I think I learned to appreciate my own country more by listening to and watching them.
