Minecraft wiki entry for Villager_(old), associated text: Upon spawning, villagers will leave their homes and begin to explore the village. Generally, they wander aimlessly inside the village during the day. They may go indoors or outdoors, and they periodically make mumbling sounds. Occasionally, two villagers may stop and turn to look at each other, in a behavior called socializing, in which they will stare at another villager for 4-5 seconds at a time. In the case of players, they will continuously stare at them as long as the player is close enough, unless the villager tries to get into a house at night, farm food, or flee from a zombie.
