Four letter words

Sitting in my office in the wee hours of a Thursday morning, I heard two men loudly arguing on the sidewalk right under my window. It seemed that every second word from each of them was a expletive that rhymes with buck. I looked down from my window to keep an eye on them until they parted ways. As I sat back down at my desk, the heaviness of their anger, the violence of their speech, and the use of their profanity got me thinking about other four-letter words. This morning’s M5T considers four-letter words to live by.
