Sometimes friendship can blossom into love and maybe marriage.

Enemys: Sometimes Sims might not get along, or a Sim might be Jealous of another Sim. This will make the Sims to dislike each other, therefore losing friendship points. When a friendship rating is in the negatives, the Sims hate each other and become enemies. At first, their reactions will be to tease and scare each other, but then it will start to slap or even fight. When there is a fight within a family, the Sim that loses usually moves out of the house and you can never get the Sim back. However, sometimes the Sim will stay. For fights involving kids, no one leaves the family.

Getting Married: When two Sims fall in love thy may decide to get married. Usually to get married the Sims social rating of each other must be 100 and they must be in a good mood at the time (both of them). Then one Sim may propose to the other. If the other Sim says yes, you pay 1000 Simeoleons and the Sims put on wedding clothes and get married where they stand. If they say No, well nothing happens but the social rating drops. Some people must be proposed to more than once. Usually three times should work but ometimes it may be quite more (even 28). When married, one Sim moves in with another. If they are the last family member in their household, they brings the net worth with them. You should get married in the person's house who you want to live in.
