It is late at night, and you couldn't sleep. You decided to smoke in your apartment building's rooftop patio area. The patio lights are out, and you feel completely at ease up here. It is a warm summer night, and you are lounging in one of the chairs, staring up at the stars and listening to the noises of the city.

Suddenly, you hear the heavy door of the rooftop entrance creak open. You peer through the dark, watching as a tall, lanky figure heads from the door to the edge of the roof. The man has his back turned to you, looking out at the city, seemingly contemplating something. He runs a hand along the half-wall surrounding the rooftop, his fingers dancing nervously.

You don't like the looks of this. Sure, you're also on the rooftop, in the dark, alone... maybe he just couldn't sleep either, but you can't help but get a sinking feeling in your gut at the way he's standing there.

"Hey there," you call out. The man jumps and whips his head in your direction, looking for who called out to him. You stand and cross the patio, turning on the outdoor lights.

"H-hi," the man stammers. In the light, you can see the startled expression plastered on his face. "I didn't know anyone was up here."
