Every stranger you meet is carrying something you cannot see.

The woman at the grocery store checkout might have just received wonderful news. Or she might have just lost someone she loved. The bus driver might be having the best day of his year. Or he might be worried about a sick child at home. You cannot know. And that is exactly the point.

Because you cannot see what people are carrying, the only safe and right way to treat them is with basic kindness and respect. Every single time.

A smile costs nothing. Holding a door costs nothing. Saying “thank you” costs nothing. Making eye contact and treating another person like a real human being — not like a machine that serves you — costs absolutely nothing.

Think about the people who make your daily life work. Someone drives the bus that takes you to school. Someone keeps the school clean. Someone stocks the shelves at the store where your family buys food. Someone picks up the trash from your street every week. These people are not invisible, even though the world sometimes treats them as if they are. See them. Acknowledge them. Thank them.

When someone helps you — anyone, anywhere — say thank you and mean it. Look them in the eyes when you say it. When you bump into someone, say “excuse me.” When you are in a line, wait your turn. When you are in a public place, keep your voice at a level that does not disturb others. When you see someone struggling — carrying heavy bags, looking lost — offer to help. A simple “Can I help you with that?” is enough. They may say no. That is fine. The offer itself matters.

Be gentle and courteous to all children you meet. Whether they are younger than you, or strangers on the playground, or the little brother tagging along with a friend — treat them with patience and kindness. There is no surer sign of a good heart than gentleness toward the small and the young.

The way you treat people who can do nothing for you reveals exactly who you are. It is easy to be polite to your teacher, because your teacher gives you grades. But how do you treat the person who has no power over you and nothing to offer you? That is the true test. The way you treat the waiter is the way you treat the world when you think no one is keeping score. Someone is always keeping score. And that someone is you — the person you are becoming, one small interaction at a time.

There is an old story that shows this perfectly.

Deep in a forest, far from any city, an old woman named Shabarī had been waiting for years. Her teacher, before he died, had told her: “Stay here. One day, God himself will visit you.” So she waited. Every morning she swept the path to her hut. Every day she gathered the sweetest fruits she could find, tasting each one first to make sure it was not sour, setting aside only the best. She did this for years — some say decades — with no proof that anyone would ever come.

Then one day, two young men appeared at her door. They were princes, wandering through the forest, tired and grieving, searching for someone they had lost. One of them was Rāma.

Shabarī was old. She was poor. She was a tribal woman living alone in the woods, with no status, no wealth, no power. In the eyes of the world, she was nobody.

But Rāma did not see a poor old woman. He saw someone who had waited a lifetime on nothing but faith and love. He sat in her simple hut and ate the fruits she offered — fruits she had already bitten into to check for sweetness — with the same respect and gratitude He would have shown a queen serving a feast in a golden palace. He treated her small offering as if it were the most precious gift He had ever received.

Because it was. A lifetime of devotion was in those fruits.

Every stranger carries a story you cannot see. The person who looks like they have nothing may be carrying something extraordinary inside them. You will never know unless you treat them with the same kindness and respect you would give anyone else.

Something else about the people you meet: not everyone is on the same journey. Some people are naturally kind — kindness is woven into their nature the way color is woven into a leaf. Some people are somewhere in the middle — sometimes kind, sometimes not, depending on the day and the pressure they are under. And some people — a small number — seem to choose darkness no matter how much light is offered to them.

This is not your problem to solve. Your job is to be kind to everyone regardless — because kindness is about who you are, not about who they are. But your job is also to be wise enough to recognize who you are dealing with. You can treat every person with dignity and still protect yourself from the ones who would take advantage of that dignity.

A truly good person will not make fun of other people’s mistakes, their ignorance, or their physical limitations — and will not even allow themselves to smile at them. They will treat the clumsiest person with the same easy courtesy they give the most graceful. Think about physical differences for a moment. Some people are very tall. Some are very short. Some have a visible disability. None of these things are within their control. Anyone who mocks something a person cannot change has revealed something ugly about themselves, not about the other person. And never speak against someone who is not there to defend themselves. This goes double when the person you are tempted to criticize has no power, no status, no one to stand up for them.

Be kind to people you do not know. Be polite to people you will never see again. Be generous with your attention and your courtesy. Not because you expect anything back. But because this is what a good person does — and because the world, with all its strangers, is the only world we have.
