When the defense was over, Professor Miller came to shake my hand and greet my family. When it was Ben’s turn, he suddenly stopped, looked closely at him, and then his expression changed.

I was born into a single-parent family. As soon as I learned to walk, my parents divorced. My mom, Laura, took me back to Cedar Creek, a poor, rural area with only cornfields, sun, wind, and gossip.

I don’t clearly remember my biological father’s face, but I know my early years lacked both material and emotional things.

When I was four, my mother remarried. That man was a construction worker. He came to my mother with nothing: no house, no money; just a thin back, tanned skin, and hands calloused from cement.

At first, I didn’t like him: he was a stranger, he left early and came home late, and he always smelled of sweat and construction dust.

But he was the first to fix my old bicycle, to quietly help me sew my broken sandals without saying a word. I made a mess, he didn’t scold me; he just cleaned it up in silence.

When I was bullied at school, he didn’t yell at me like my mother; he simply went to pick me up on his old bicycle. On the way, he only said one sentence:

— “Ben doesn’t force you to call me Dad, but Ben will always be behind you if you need me.“

I kept silent. But from that day on, I started calling him Ben.

During my childhood, my memories of Ben were of an old bicycle, a dusty construction uniform, and the nights he came home late, with dark circles under his eyes and hands still covered in plaster and mortar. No matter how late it was, he never forgot to ask:

— “How was school today?“

He didn’t have a high level of education, he couldn’t explain difficult equations or complex paragraphs, but he always emphasized:

— “You might not be the best in the class, but you must study well. Wherever you go, people will value your knowledge and respect you.“

My mother was a farm worker, and Ben was a construction worker. The family lived on meager earnings. I was a good student, but I understood the situation and didn’t dare to dream big.

When I passed the university entrance exam in Boston, my mother cried; Ben sat on the porch, smoking a cheap cigarette. The next day, he sold his only motorcycle and gathered his mother’s savings to send me to school.

The day he took me to the city, Ben wore an old cap, a wrinkled shirt, and his back was soaked with sweat, but he still held a box of “gifts from home”: a few pounds of rice, a jar of dried fish, and some bags of roasted peanuts. Before leaving the dorm, he looked at me:

— “Do your best, son. Study well.“

I didn’t cry. But when I opened the lunchbox my mother had wrapped in foil, underneath there was a piece of paper folded into quarters, with scribbled words:

— “Ben doesn’t know what you’re studying, but whatever you study, Ben will work hard for it. Don’t worry.“

I studied four years in college and then in graduate school. Ben kept working. His hands became rougher, his back more and more stooped.

When I returned home, I saw him sitting at the foot of the scaffolding, panting from having climbed all day, and my heart turned over. I told him to rest, but he waved his hand:

— “Ben can still do it. When I’m tired, I think: ‘I’m raising a Ph.D., and I feel proud.’“

I smiled, not daring to say that studying for a Ph.D. requires extra work, requires even more effort. But he was the reason I didn’t allow myself to give up.

On the day of my doctoral thesis defense at Boston University, I begged Ben for a long time until he agreed to go.

He borrowed a suit from his cousin, wore shoes that were a size too small, and a new hat he bought at the district market. He sat in the last row of the auditorium, trying to straighten up, never taking his eyes off me.

After the defense, Professor Miller shook my hand and my family’s. Upon reaching Ben, he suddenly stopped, looked closely, and smiled:

— “You’re Ben, aren’t you? When I was young, my house was near a construction site where you worked in Queens. I remember the time you helped an injured worker down from the scaffolding, even though you were also injured.“

Before Ben could say anything, the professor was already… moved:

— “I didn’t expect to see you here today, as the father of a new doctor. It is a true honor.“

I turned around: Ben smiled, a kind smile, but his eyes were red. At that moment, I understood: in his entire life, he had never asked me to repay him. Today, he was recognized, not because of me, but for what he had quietly sown for 25 years.

Now I am a university professor in Boston, with a small family. Ben no longer builds: he grows vegetables, raises chickens, reads the newspaper in the morning, and rides his bike around the neighborhood in the afternoon.

Occasionally, he calls me to show me the vegetable gardens behind the house and tells me to come buy chickens and eggs for my grandson to eat. I ask him:

— “Ben, do you regret working hard all your life for your son?“

He laughs:

— “I don’t regret it. Ben has worked all his life, but what he is most proud of is having raised a son like you.“

I don’t reply. I just look at his hands on the screen: the hands that hold my future.

I am a doctor. Ben is a construction worker. He didn’t build me a house, but a person.
