The Sims 2/Social Interactions

The social need has so many ways to fill it and their all rewarding in their own right. In fact, one page alone can't describe all the social interactions. That's why they've been split up into three pages. Normal interactions can be performed to any sim. Romantic interactions can't be performed to family members and family interactions can only be performed to family members. Now for some basic information on the relationship score.
 * Romantic
 * Family
 * Normal

Relationship Scores
Relationships are split up into two scores: Daily and Lifetime. Daily represents short-term relationships and is volatile. Lifetime represents long-term relationships and is not as volatile as daily. This is because only a few interactions can increase or decrease it. Both relationship types can change numbers without any influence, however the way they do so is different.

Daily Relationship
Daily relationship is an extremely volatile score. It's easy to build up but is just as easy to decrease. It can also decay over time. Every day at 4pm, each sims daily will drop by two points. This can also break friendships as they must be mutual. At that time, you may be pestered with phone calls from other sims your sim knows asking to be socialized with. If you want to keep relationship high, this should be taken as a wake-up call

Lifetime Relationship
Lifetime relationship is more stable than daily. Instead of decaying, it normalizes. Three times a day, the lifetime will shift towards daily score by three. There are few interactions that raise lifetime and most of them are romantic.

Availability and Acceptance
On the other pages you may see the terms availability and acceptance. For clarity these terms are defined here. Availability refers to whether a social interaction can be initiated on a sim. Think of it as an unlockable system of sorts where increasing score gives you more interactions.

Acceptance is whether a social interaction goes right. When you initiate an interaction, certain criteria must be met for it to be accepted. This is why newly unlocked interactions may go wrong when initiated.

Exceptions
There are plenty of exceptions to these rules for social interactions. The list is as follows.

Aspiration Rewards
The following aspiration rewards make it easier to perform social interactions.
 * Cool Shades. The shades amplify the outcome of the first social interaction performed after the shades are worn
 * Love Tub. The Love Tub seems like a normal hot tub but lowers requirements for all social interactions performed within it. This only applies until the candles included with it burn out.

Chemistry (Nightlife)
Chemistry, like the Love Tub, reduces requirements for various socials. For more information see Attraction and Chemistry

Seasons (Seasons)
Various seasons amplify types of social interactions.
 * Summer. Summer amplifies normal interactions.
 * Spring. Spring amplifies romantic interactions.
 * Winter. Winter amplifies normal interactions between household and family members.

Vacation Destinations (Bon Voyage)
Some vacation destination types amplify social interactions.
 * Island. Island destinations amplify romantic socials.
 * Mountains. Mountains amplify normal interactions. This is why, if you have Seasons installed, the relationship boost sign shows the summer boost icon, even though the preset seasons are Autumn and Winter.

Social Bunny
The bunny is an imaginary enemy. True to it's name, you must never socialize. Have your sims make enemies with each other. You really can't have social interactions, so you must have negative interactions. Then the need for social imagination kinda cries... For example, a lonely Sim can poke and shove it. Most Sims are in the mood to work on Body skill before the bunny arrives. Reach the skill to level 10. If the bunny arrives, a few players would delete the bunny. It is possible to let the Social Bunny die by hail (Seasons is needed). The Social Bunny sometimes cannot be added to the family. However, it can be created with CAS debugging mode. Adding Social Bunny to the family, making it pregnant, or interacting with it some other way outside the game can all cause game corruption. The Social Bunny cannot talk, however. It jumps and follows you. If there are any objects or walls that are blocking it, it would teleport. Please shoo it. If there are children, it will instead take them away.
