It was an ordinary Friday afternoon. While the students were eating lunch, I walked down the hallway of my elementary school's main building and stopped by the office to check my mail. I had to hurry because my students eat lunch in about two minutes so they can dash back to class for a guitar lesson. It's something they love to learn. As I sorted through my mail, I saw a fellow teacher glumly enter the office. It looked like she was having a hard day, so I tried to cheer her up. "Happy Friday," I said with a smile.

"I hate Fridays," she responded curtly. "It just means that Monday is that much sooner."
