The daughter-in-law changed the bed sheets almost every day, explaining it with her love for cleanliness: but one day the mother-in-law lifted the blanket, saw a strange mark on the sheet, and learned a terrible secret about her daughter-in-law 

When my son Daniel married Sofia, I sincerely thought that fate had given us a great gift. She seemed to be exactly the kind of girl every mother dreams of for her son. Calm, well-mannered, attentive, and surprisingly patient.

They met while studying at university. After a year of dating, Daniel brought her to meet me. I remember that evening very well. Sofia spoke quietly and politely and even helped me set the table.

After that evening, many people told me the same thing:

— You are very lucky. A girl like that will make your son happy.

I thought so too.

After the wedding, they moved into a small guest house behind my home. I wanted them to have their own space, but at the same time there would be a chance to help them if they needed anything.

From the outside, their life looked almost perfect.

Almost. Because Sofia had one strange habit that I simply couldn’t understand.

Every morning she completely removed all the bedding. Sheets, pillowcases, duvet cover — everything went straight into the wash.

At first I thought she simply loved cleanliness too much. But after a few weeks it began to seem strange.

One day I asked her carefully:

— Sofia, dear, why do you wash the bed sheets every day? You’ll get tired.

She smiled and continued hanging the sheets on the line.

— It’s nothing serious. I just sleep better with fresh sheets.

The answer was calm, but something uneasy flashed in her eyes. It seemed as if she was afraid of something or hiding something.

I decided not to press her. However, weeks passed and her habit didn’t change.

One Saturday morning I said I was going to the market. Sofia waved to me from the porch while I started the car. I even honked goodbye.

But instead of driving into town, I parked around the corner and a few minutes later quietly returned through the side gate.

When I entered their small guest house, a smell immediately made me uneasy.

There was a heavy metallic smell in the air that was impossible to confuse with anything else.

I slowly walked toward the bedroom. The bed was already made. But some strange feeling made me pull the sheet up.

And at that moment my breath caught. There were dark stains on the mattress. 

That day I learned a terrible secret about my daughter-in-law, whom I had always considered perfect.  The continuation of the story can be found in the first comment 

There were too many for it to be explained by coincidence. I stepped back, feeling my heart begin to beat faster and faster.

From the kitchen came Sofia’s quiet humming. She was preparing breakfast and seemed to suspect nothing.

I couldn’t stand it and called her. She walked into the room and immediately understood everything. From her face it was clear she knew — this moment would come someday.

Sofia stayed silent for a long time. Then she said quietly:

— Please… don’t be scared.

I looked at her and waited for an answer.

She took a deep breath.

— It’s not mine.

For a second, the world seemed to stop.

— Then whose is it? — I asked.

Sofia lowered her eyes.

— Daniel’s.

I felt a cold wave run through my entire body. She stepped closer and began speaking almost in a whisper:

— A few months ago doctors discovered he has a serious illness. He is undergoing treatment, but he asked me not to tell anyone… especially you.

I remained silent, unable to say a single word.

— He said you worry about him too much. He didn’t want you to live in fear for your child again. So we decided to handle it ourselves.

Sofia looked at me with tired eyes.

— That’s why I wash the sheets every day. I’m just trying to hide it so you wouldn’t find out.

At that moment I realized one simple thing. My daughter-in-law wasn’t hiding anything out of bad intentions. She was simply protecting my son.
