It happened a week before my senior year of high school. I'd gone over to a friend’s house to hang out with him and another friend, and the three of us sat on the front porch in our hometown of Allentown, Pennsylvania, talking and trying to make the best of the scorching 90-degree weather.
At one point, my friend and I got into an argument and decided to take the conversation to the side of the house, where we could talk it out privately. As we went back and forth, I looked down at my phone. My friend fidgeted with his pocketknife, scraping it along the bricks on the side of the house as we leaned against the wall.
