While waiting in line at the grocery store, I once saw a woman I had never met before start talking to a baby sitting in a car seat. She began by complimenting the baby's shoes and continued on to say how pretty the baby's eyes were, while I awkwardly smiled from the side.

This kind of scene happens not just in grocery stores but also in cafes, parks, and even bank lines. Even when a stroller passes by, a nearby stranger might bend down to greet the child.

When I first came to the U.S., these situations felt strange every time. In Korea, I had rarely seen adults initiate conversations with unfamiliar children.

However, over time, I learned that this is not just a quirk of certain individuals but a habit ingrained in American society as a whole.

Americans are said to be quite uncomfortable with silence. Whether in an elevator or while waiting in line, there is a strong tendency to fill the silence with conversation.

In fact, a research team led by behavioral scientist Nicholas Epley at the University of Chicago once had commuters on trains and buses engage in conversations with strangers sitting next to them, and the results were quite surprising. Everyone expected that people would prefer to travel quietly alone, but those who engaged in conversation reported having a more enjoyable journey.

Topics like the weather or sports, which are politically neutral and low-pressure, are often used for small talk, and few subjects are as safe as talking about children.

While complimenting an adult outright might come off as rude or burdensome, it's different with children. Saying a child's outfit is cute or that they have a beautiful smile doesn't hurt anyone.

There's an interesting point in research by Cornell University social psychologist Vanessa Bohns. People often assume that the recipient of a compliment will feel uncomfortable, but in reality, they tend to enjoy it much more than expected.

This experiment was originally conducted by having participants compliment the clothing of passing strangers on campus. The ones giving the compliments worried that the recipients would feel uncomfortable or slightly annoyed, but even after seeing the positive reactions, they continued to underestimate how much the recipients appreciated the compliments.

The old saying that it takes a village to raise a child is often cited in the U.S. In that brief moment when a stranger talks to a child, there's an underlying sentiment that the eyes watching over that child are not just one person's.

In other words, Americans are not particularly brave for talking to strange children; rather, there's a social agreement that such kindness will be willingly accepted.

The American way of complimenting also plays a role. Instead of simply saying a child is cute, they might exaggerate it by saying they are incredibly cute or have star potential, which is a unique American way of speaking. This exaggerated positivity helps to quickly dissolve any awkwardness between strangers.

It's also interesting that in neighborhoods where various races and languages mix, such greetings feel even more natural. The common ground of children lowers the threshold for conversation among neighbors from different backgrounds.

Interestingly, this habit seems quite communal for a society that prides itself on individualism. While it's a country where everyone is expected to take care of themselves, in front of children, people tend to become neighbors, even if just for a moment.

Of course, not everyone welcomes this kind of interaction. Some parents feel uncomfortable with strangers approaching their children, and there's a growing voice advocating for greater respect for children's privacy and personal space as generations change.

For this reason, it's true that people have become more cautious than before. There's a sense that touching a child's head or body is being avoided, and the trend is shifting towards expressing kindness verbally.

However, statistics show that these worries may be greater than reality. According to data from the National Center for Missing & Exploited Children, abductions by strangers account for only about 1 percent of all missing person reports, making it statistically a rare occurrence.

For those who have recently immigrated, it can be unclear how to respond in these situations, but simply smiling and saying a quick thank you is usually sufficient. There's no need to extend the conversation, as just sharing a brief smile already integrates you into this culture.

Still, I believe this culture itself is not a bad thing. It allows people from different backgrounds and languages to share a moment of laughter and conversation through a single child.

Multiculturalism isn't something grand; it starts with these small moments of opening up to each other, even if just briefly.

At first, I thought this was a bit cheesy, but looking back, it turned out to be quite a nice habit. There aren't many places where the kindness of strangers remains a natural part of the neighborhood landscape.

These days, when I see an adult talking to a strange child, I actually feel happy. That brief greeting seems to make the neighborhood a little more livable.
