Relationship

Sim Relationships
As soon as a Sim meets another they accumulate relationship points. The amount of points two Sims have for each other and their life stages determines how they can interact. When Sims interact with each other, they build daily relationships. Over time, two Sims' lifetime relationships will build up as long as they continue to interact. Sim relationships could also grow up or down with the use of cheats.

Pet Relationships
Pets can also develop relationships. Pets develop relationships with Sims by doing positive interactions, such as praising, playing, or giving love. Negative relationship points are given when a Sim scolds or yells at a pet. When teaching a pet tricks, the relationship goes up and down, depending on how fast the pet learns, but in the end is higher.
