A "favor" is a kind act or service that one person does for another without expecting anything in return. Favors can range from small gestures, like helping a friend carry groceries, to larger acts, such as lending someone money. They often strengthen relationships and build goodwill between individuals. Favors are commonly exchanged in social settings, where people may ask for help or assistance. This can occur in various contexts, such as among friends, family, or colleagues. The concept of favors is closely related to the idea of reciprocity, where individuals feel inclined to return the kindness shown to them by others.
