Opinions on emotions?

I don't like the Mood swings, you try to do something and there goes your sim, weather to happy to do the simple task YOU want them to do, while they sit there every 3 sec laughing or they walk into another room and are to mad to even do it.
They spend to much time on their emotions then letting you play your game, your way.
It's way to over emotional and to bipolar.
Talk about mood swings.
