First of all, feeling the kindness of strangers will make us feel concerned and valued, and bring us a sense of pleasure and satisfaction. People are naturally eager to connect with others and gain recognition, and this demand is particularly obvious in the social media era.

Secondly, the kindness of strangers will also arouse our inner empathy and gratitude. When we feel the help and support of others, we are not only receiving care, but also naturally want to repay these feelings and behaviors.

Finally, for some people, being moved by the kindness of strangers may also be because they lack self-confidence or have low trust in themselves. In this case, they may need to gain self-affirmation and recognition of their own value from the outside.
