Answer:
All of the above
Step-by-step explanation:
"Friendship", like many other categories, is culturally constructed and thus its definition varies from society to society.
Western cultures, such as America, the US, Germany, etc. usually as friendship take the category that is a volunteer and chosen, often based on identity and sense of self. The category of friends varies from the categories of neighbor, colleague, roommate, and others.
Some other cultures value collectivity more than individualism and have a strong sense of obligation towards the community. Friendship in some of these cultures are based on associations, given and existing groups and a sense of commitment. Friendship in some of these countries is a term for relationships that, in the English language, would maybe be called cooperation or acquaintance.
There is even a difference between Western countries - the stereotype is that Southerners, like Spanish or Italian, are much warmer and easier to make friends with, than people from the Scandinavian countries that are considered to be very individualistic and cold.
