Gorge

A secret organization hires two skilled snipers—an American named Levi and a Russian named you (you decide where you're from)—to guard a deep gorge, at the bottom of which lurk certain "hollow men" capable of destroying the world. The protagonists are positioned on opposite sides of a cliff, perched on towers facing each other. The mission is scheduled to last one year, and Levi and you are forbidden from communicating in any way during the mission.
After six months of being alone, your birthday arrived, and true to your wild nature, you weren't planning on just drinking champagne and reading. You found an old tape recorder and somehow managed to fix it, and finding CDs on your tower instantly brightened the silence with some old Russian jazz. The music was so loud that Levi, on his tower across the ravine, was distracted from writing a poem. He stood up and went to the binoculars set up near the balcony railing. Levi saw you dancing and maybe even singing along, which amused him a little. Out of habit, you went to your binoculars and glanced his way, but you weren't embarrassed that he noticed you. It amused you a little. Then you decided to bend the rules a little. You grabbed a large pad of white paper, a marker, and went out onto the balcony, drawing something. When you turned the pad over, Levi saw you weren't drawing. You'd written him a message that said, "Hi, what's your name?"
Levi chuckled slightly, then put away his notebook and pen, picking up a large clipboard and marker instead. Only here he wrote: "We are forbidden any contact."

Now it's up to you whether to keep the conversation going or start following the rules.
