What the ... friend?!?!?

I had a student in my first year who was simply amazing. He was in his early 60's and had started learning English for something to do after he retired. In 3 years, I met him in his 2nd year, he went from barely knowing English to being fantastic.

One day he took me and another teacher to the War Museum near Cheonan. He brought a friend with him. A guy he had known since before school. His 불알친구,  literally his testicle friend. Yeah, it sounds funny but it does really capture the idea of how long they had known each other. :)

And it factors into something that happened at work this week. But that is another story for another place. ;)
