The afternoon sun streamed through the window, warming Leo’s face as he waited. The receptionist, a woman with a perpetually surprised expression, had just buzzed him through. He bounced on the balls of his feet, feeling a lightness in his chest. His old nemesis, Brenda “The Bruiser” Baker, a therapist? The irony was delicious.

He found her office easily enough. The door was slightly ajar, revealing Brenda seated behind a large desk. The desk was covered in what looked like soft things, like stress balls shaped like kittens. Leo knocked, just once, and watched her start.

“Leo…?” Brenda asked slowly, her face a mask of bewilderment.

“The one and only,” he said, his voice brimming with an irrepressible energy. “Just thought I’d take a peek at your domain. You know, see how you’re doing.” He gestured widely around the room. “Interesting décor.”
