Friendship is a human relationship which involves mutual knowledge, esteem, and affection. Friends will welcome each other's company and exhibit loyalty towards each other, often to the point of putting the other's interest before one's own. Their tastes will be similar and may converge, and they will share enjoyable activities. They will also engage in mutually helping behavior, such as exchange of advice and the sharing of hardship.

In a comparison of personal relationships, friendship is considered to be closer than acquaintanceship, although there is a range of degrees of intimacy in both friendships and acquaintances. For many people, friendship and acquaintanceship lie along the same continuum.
