Would you like to buy food or drinks for a stranger? Do you know what "paying it forward" means? It's to do something nice for another person for no reason. Then that person does something nice for someone else. You might think that this doesn't seem like much. But the kind act can spread really fast.
One day in December, 2015, an American woman was buying a meal. She also bought a meal for the person standing in line behind her. That person did the same thing, and the next person did, too. Soon, 250 people bought meals for another!
But you don't have to spend money to pay it forward. There are examples of paying it forward every day like giving food to the homeless or doing something extra nice for someone around you.
Have a try and bring happiness to others. All you can do is look for little things you could do to make a person's day. Then, ask them to do three kind things for someone else. And when someone does something nice for you, don't forget to do the same!
