My coworker brought me coffee every Monday for a month. I thought she was just being nice. When she quit, I found a note on her PC screen.

It said: “Things to do: make someone happy on Monday. Make someone feel seen.” After some time it turned out that simple gesture had started something I never expected. Her name was Lidia.

She wasn’t the loudest in the office, nor the one who stood out in meetings. But she smiled often, especially on Mondays, which always struck me as odd. Everyone else dragged themselves in like zombies, while Lidia waltzed in with two coffees—one for herself, one for me.

I never asked why. I just thanked her each time. Sometimes I offered to return the favor, but she’d wave me off and say, “Maybe one day.”

Then one Monday she didn’t show up.

Her desk was empty. Later that morning, the manager announced she had quit suddenly over the weekend. No explanation, no farewell email, nothing.

As people murmured in surprise, I sat back in my chair and looked toward her desk. Her coffee mug still sat there, clean. Her chair was neatly pushed in.

I wandered over, thinking maybe she left something behind. That’s when I saw it—the note stuck to her monitor. “Things to do: make someone happy on Monday.

Make someone feel seen.”

I stared at those words for a long time. They weren’t dramatic. Just… real.

Human. Honest. That night, I kept thinking about it.

What kind of person writes that on a Post-it? And more importantly, why did she choose me? I wasn’t particularly cheerful at work.

I came in, did my job, left. I was polite, but kept to myself. Mondays were always the worst.

I’d lost my brother two years prior, on a Monday. Since then, I dreaded them like clockwork. I never told anyone.

Yet somehow, Lidia saw something. Weeks passed. I missed those small moments—the warm cup of coffee already on my desk, the tiny smile she’d give as she walked away.

The silence she left behind felt louder than anything else. Then one Monday, I did something I never usually did. I brought two coffees to work.

One I placed on my desk. The other, I set down at the new intern’s cubicle. His name was Sam.

He looked about 22, always hunched over his laptop, headphones in, barely speaking. He glanced up, confused. “This for me?”

“Yeah,” I said, offering a smile.

“Mondays suck less with coffee.”

He smiled faintly, nodded, and took a sip. We didn’t talk much. But I kept doing it.

Every Monday. Sometimes we chatted for a few minutes. He told me about his long commute, about how he wasn’t sure he was cut out for corporate life.

I didn’t push. Just listened. Then, one Monday, Sam didn’t show up.

My heart sank. Not again, I thought. But around 10 AM, he walked in, holding two coffees.

He placed one on my desk. “I figured,” he said with a half-smile, “maybe it’s my turn.”

We both laughed. What started as a small thing became something more.

Others in the office noticed. Someone brought cookies the next Monday. Someone else left sticky notes with jokes on desks.

It wasn’t planned. It just… happened. A ripple effect.

I never told anyone about Lidia’s note. It felt like our secret. But what she started didn’t stop with her.

Months passed. Sam got promoted. He told me one day over lunch that those Monday coffees helped him through a really dark time.

He’d just lost his dad before starting the job. Didn’t think he’d last a month. I nodded quietly, swallowing the lump in my throat.

He asked why I started giving him coffee. I told him about Lidia. About the note.

He didn’t say anything for a while. Just looked out the window and said, “Funny how one small thing can echo like that.”

It was. But the story doesn’t end there.

One afternoon, I was in a bookstore near my apartment. I stopped by a shelf on mindfulness and saw a familiar name on a book spine: “You Are Seen” by Lidia N. Marcovici.

I froze. I picked it up and flipped to the back cover. It was her.

Lidia. Her photo was right there, smiling that same calm smile she always had. The book was about small acts of kindness.

About how she’d challenged herself for a year to do one small thing every Monday for someone else. Some weeks it was leaving change taped to a vending machine. Other times, it was a compliment, a ride, or a coffee.

She called it “Monday Miracles.”

And she wrote that her favorite experience was with a coworker who didn’t say much, but always said thank you. She never asked for anything back. Just accepted the coffee like it was part of their routine.

She wrote, “He never knew, but I chose him because he looked like he carried something heavy. I didn’t want to fix it. I just wanted him to know someone saw him.”

I sat down right there in the aisle and cried.

I bought ten copies. The next Monday, I left one on the desk of every person who had ever joined in the Monday kindness chain at work. I taped a note to each: “You are seen.”

No one asked where the books came from.

But they were read. Years passed. I moved on to another company eventually.

Started in management. Mondays were still hard sometimes, but I had a ritual. Coffee.

A kind word. A reminder. Then one day, I got an email.

Subject: You Changed My Life. It was from a woman named Ana, a former intern. She had worked in the same building as my old company.
