Text exchange with my redheaded former student Darcy:
Me: "I was driving through campus and saw a dorky redheaded student carrying a huge stack of books and wearing a poseur turtleneck and beret and nerd glasses. It made me all nostalgic. I tried to hit her with my door, but she was too fast."
Darcy: "And I thought of you yesterday when I thought I'd stepped in something but it turned out to be nothing."
