What are some underrated features of your favorite packs?

This is from Get Together: I really like that you can influence sims to "hookup" with another sim. If they like the sim, they'll start dating. You can also "Talk up" a sim and improve that sim's relationship with another sim. I also love being able to trash talk other sims. And, if you trash talk someone else who is in the same room, the sim you are talking to will go up to that sim and yell at them :D
