The message notification shimmered on the screen: "Mr. Harrison is following you." Emily felt a quickening in her pulse. He had been her drama teacher, the man who’d coaxed her out of her shell, the one who’d believed in her when she didn't believe in herself. She started scrolling, her heart beating a little faster. His profile was filled with pictures of theater productions, both then and now. Her throat tightened. The feeling was a strange, bittersweet mix of joy and sadness. A deep longing for the collaborative energy of those years washed over her.
