I didn't really know that however the bed thing only works when the bottom of the bed is not against the wall.
Here is my contribution the Stainless steal auto-pot when the aura is activated will fire the dominate emotion to all sims. To activate this, which is a two step process one sim has to stand next to it until they get the environmental moodlet which is +2 now anyone that is in your group will also get that moodlet and the coffee pot will fire the dominate mood in the room to all sims near the pot.
Cow plants can also eat negative emotions. Sad and angry sims can eat the cake of a cow plant to clear the negative emotions. NPC sims if Sad will eat cow plant cake autonomously. The embarrassment moodlet around friends and at home is less than in public or at another house. Children and Teen Sims can't die from being Very Angry, Very Embarrassed, and Very Playful. Teens and Kids can't get to +8 in any emotion that will kill an adult.
Edit:
Trying for a baby and the other kid walks in, if pregnant and you share the good news the kid will react negatively for the new addiction. The kid will be sad until the kid is born and if a lonely child, your get a moodlet competing for moms attention or have to share my stuff now.
