My best friend in high school ended our friendship in a letter. She was a year older and in her first year of college in a different city. In the letter she listed a number of issues she had with me. Of all the words she wrote me in that two-paged front-and-back handwritten missive, I vividly remember reading: “And you’re too quiet sometimes! It’s like: talk!” The words struck me with as much force as if she’d come back to town just to punch me in my stomach.
