TPM #2 (Feuds)

Sorry it's been so long between posts, Mid-Quarter exams are rough. But they did provide me with a new TPM idea. A student of mine recently came up to me after a mid term exam and expressed that there was a feud going on about my class. I was confused and asked him who was involved in the feud. He told me that it was a feud in his head about whether or not he should stay in my class. At first I laughed (feuds have to be between two or more people right?) but then I realized I may be being naive and that the word feud may have a broader definition than I previously thought. Whatever the definition of feud, this incident inspired me to think about the great feuds of all time which will be the topic of my upcoming posts.
