if you need friends then make a room with the most expensive wallpaper en carpet and put a 2 person bed in it (and a door). cal a sim at (almost exactly) 6:00 or 6:30, then make him/her go RELAX in the bed go also there in the bed and delete the door and make a wall (so close as possbile) around the bed and watch the friendship and social rise. HINT: do this when YOURE sim also is tired that is a handy time saver

NOTE:this also works on OTHER platforms of the sims.
