Let's talk about the flawed emotion system

My issue with the emotion system is that the moods change too easily. & I've said it in other threads, everything is 'happy, happy'. My Sim just caught her spouse cheating. She get hits with the jealousy moodlet for 24 hours, but something over powers it & 2 seconds later she can have a happy conversation with him. Or if my Sim gets into a fight, he'll be angry for a minute, but 2 seconds later can have a happy conversation with the person that just beat him up. I get a bit frustrated with this, as I want the emotions and their moods to stick. I hate to go back to another game, but look at TS2. If a Sim got caught cheating, there was no way you could have a 'happy' conversation with them; it wasn't happening. They would have 'fury' & there was a cool off period before you could even have a pleasant convo with them. I'm not sure what needs to happen in TS4 , but I'd like to see more consequences & some of the 'negative' emotions stick for a more in depth game play experience.
