A gift or a present is an item given to someone without the expectation of payment or return. An item is not a gift, if that item, itself, is already owned by the one to whom it is given. Although gift-giving might involve an expectation of reciprocity, a gift is meant to be free. In many countries, the act of mutually exchanging money, goods, etc. may sustain social relations and contribute to social cohesion. Economists have elaborated the economics of gift-giving into the notion of a gift economy.
By extension the term gift can refer to anything that makes the other happier or less sad, especially as a favor, including forgiveness and kindness. Gifts are also first and foremost presented on occasions - birthdays and, in Western cultures, Christmas being the main examples and other occasions like birthdays.
In many cultures gifts are traditionally packaged in some way. For example, in Western cultures, gifts are often wrapped in wrapping paper and accompanied by a gift note which may note the occasion, the recipient's name, and the giver's name. In Chinese culture, red wrapping connotes luck. Although inexpensive gifts are common among colleagues, associates and acquaintances, expensive or amorous gifts are considered more appropriate among close friends, romantic interests or relatives.
