It felt like her heart was doing summersaults in her chest as she waited. John, the "video game developer," was usually so secretive about his work. Heโ€™d given her a specific address, a non-descript building in the city. Now, to see if his stories were as fantastical as she thought.

The door of the building opened. A man, wearing a headset, emerged carrying a box of pizza. Inside, she saw a large group of teenagers crammed into a room, all playing video games. John, in his usual attire, was cheering them on. A chortle escaped her lips.

John spotted her. "Hey! What are you doing here?" he asked, startled. "Oh, John, what a *fantastic* turn of events!" she gushed. "It just so happens, Iโ€™m starving. Where's the pizza, and tell me all about your newest game!" She grabbed his arm.
