The sign in the window read: "The Cozy Corner Cafe: Closing." Emily, a woman who rarely showed any emotion at all, found herself grinning. A strange sensation, like bubbles, started to fill her. She grabbed her phone and made a reservation for one.

She arrived at the cafe with a bright red hat and a box of silly toys. She began telling stories to the waitress, inventing outlandish characters and situations. She peppered her order with quirky requests.

She pulled out her camera and took pictures of her meal, making funny faces. She left a drawing on the table for the staff. She felt as though a weight had been lifted from her shoulders.
