Not all people have the luxury to buy fancy items. Some people might not have enough to buy clothes. But everyone can offer something to someone regardless of culture, religion, or race.
There are people who act selflessly even to complete strangers and these people know the value of humanity. The value we should be practicing. There are a lot more you can offer than you can imagine. No matter who you are or where you come from, you can always make a difference. And that act is the true definition of being a hero.
