Friendship

In the, Friendship is a measurement of how friendly the player is with a villager. Friendship is measured in a scale where positive represents friendship and negative represents dislike.

Improving Friendship
The player's friendship level can be increased by doing things that make them feel better, such as sending them presents or doing favors for them. Conversely, acting rudely toward the villager, such as by insulting them or hitting them with a net, lowers the player's friendship level with the villager.

Animal Crossing: City Folk
When the player waves at a villager in Animal Crossing: City Folk, the villager responds in a way that indicates their friendship level. In order to wave at a villager, the player taps them with the Wii remote when they are about five spaces away from them.

A villager who dislikes the player will ignore them, one who likes the player will bow, and a villager who is friends with the player will wave back.
