One evening, after the fourth winter of livestreaming, Rhea posted a short, unedited clip. She walked down to the corner bookstore and sat in the back under a leaking skylight, flipping a copy of the same coffee-stained paperback from her first video. “I miss not knowing if anyone cared,” she said, and the comment thread filled with love notes: “We do.” A viewer wrote that they’d taught their child the proper way to fold a fitted sheet because of her; another said they’d gone back to college to become a pastry chef after watching her gentle failures and slow successes.
