We live in a forested, mountainous region. Even in the summer, it's sometimes easy to get lost. Once autumn comes and the fog rolls in at noon, it is nearly impossible to get home. That's why our wives call to us from our houses when we head from the pasture. We whistle back, and that's how we find our home again. We make sure to follow only our wives' calls.

Mark, my neighbor, stood in the fog. The man before him just disappeared into it, following his wife's calls. Mark put his fingers in his mouth and whistled, but nothing came back. He whistled again. Nothing. He looked back at me, his brows furrowed.

"Try again."

He put his fingers in his mouth, took a deep breath, and blew the loudest whistle I had ever heard. 

Silence.

"What the hell, Tom? This never happened."

"I don't know. Maybe Mary fell asleep. Let's go to mine. It's right by yours. You'll find your way from there."

"I can only follow my wife's calls."

"That's just a saying."

"Tom."

"Alright, just imagine you are following me, okay?"

He shook his head.

"You have a better idea?"

He looked at me, then back at the fog. It was so dense you couldn't even see the trees around us.

"No."

I stood before him and whistled. A few seconds later, my wife's call came, a simple, melodic tune that broke off at the end. She always missed the last tone.

"That's it."

Mark nodded.

I kept whistling, and my wife kept calling back until we were by our porch. She smiled until she saw Mark come out of the fog too.

"Mark, why aren't you going to your wife's calls?"

"She didn't answer my whistles," he said quietly.

My wife put her hand before her mouth.

"Is she okay? I didn't come and talk to her this morning. I just had too much to do." Her voice shook.

"We'll go check on her now."

"I'll come with you."

"No, stay here. I'm sure everything's alright," I told her.

I wasn't sure, but Mark's eyes were already filled with fear. I didn't want to scare him more.

"Thank you for getting me home, Sally," Mark said and rushed toward his house.

"I'll see you later, love."

"Tom, wait!" my wife called, but I rushed after Mark. He walked so fast. I almost lost him in the fog. It was so dense, you could probably cut through it with a knife.

"Jesus," I heard Mark call a few steps before me. His front door was wide open, and the fog had drifted in, coating his furniture with dew.

"Mary?!" Mark called.

No one answered. 

"Mary?!"

Silence.

He turned to me. His lips quivered.

"Tom, where is she?! Why would she go out in the fog?"

"I don't know, Mark, I…"

Then a melody cut through my voice. The one we both knew. Mary was singing in perfect pitch from the forest in front of Mark's house.

His eyes widened, and his mouth fell open. He put his fingers in his mouth and whistled. The melody came back again.

Mark pushed me aside and ran out. Without thinking, I followed. Twigs kept hitting my face, and mud covered the ground, making me slip.

"Mark, stop!"

But his whistles kept coming, followed by that melodic voice. Only then had I realized how perfectly pitched it was. Mary had never been very good at singing.

"Mark!"

He finally stopped and looked back.

"Mark, we have to think."

"She must be somewhere around here."

"Why would she be in the forest?"

"I don't know, Tom, but she's here!"

The perfect pitch came from right behind us. My feet froze in the cold mud. Mark turned and walked toward it. I raised my hands to stop him.

"Mark, think, we just came from there."

"Get out of the way."

He pushed me to the side. I almost fell into the mud. Mark whistled again, but his whistle didn't echo. Instead, a strange silence came. 

Then Mark's heels lifted off the ground. His body tensed. He tried to put them back down, but his feet rose instead.

"Hey!"

His body floated further up. His face grew red. His eyes flew open. He grabbed his neck and kicked his feet.

"Mark!"

I ran to him and tried to grab his legs, but he was floating too high up. His whole body twisted. His stomach now faced toward the ground. His arms were still at his neck. His pleading, bloodshot eyes stared into mine. I tried to jump and reach him, but my fingers only grazed him. I jumped up again; a sharp, wet crack echoed through the forest, followed by Mark's screams. His warm blood poured onto my face. His arms flailed to the side. He let out a bloodcurdling scream, but in an instant he was gone. His screams echoed in the distance, but slowly died too.

My whole body trembled. I couldn't even move my arms to wipe my face. Then, through the silence, Mary's call came, perfect again, followed by Mark's whistling. This finally unfroze my body. I wiped my face and bolted out of the forest. The fog seemed to grow denser. My legs kept slipping on the mud. Each second, I expected to start floating too, but before I knew it, I was out of the forest, still breathing.

Mark's house stood there, but I looked away and walked back to my place. I kept replaying what happened in that forest, trying to figure out what I would even tell my wife, but as I got to my house, I saw our front door. It was open just like Mark's. The fog had rolled in too. 

From behind me, out of the forest, I heard my wife's call, perfect, just like Mary's. I stood there for a second, thinking, but I knew there was just one thing to do. I turned and whistled back.
