It is about time that Sims took more notice of their environment

I would really love to see sims react to and explore their environments more. I would especially enjoy seeing it when they move into a new home. I do a lot of rags to riches style play and it is always a little disappointing when I finally move them into their dream home and there is no reaction at all. I know it sounds silly but I want jumping up and down, hands clapping and maybe actual squealing with excitement. Then I want to see them running from room to room with excitement or possible disappointment depending on the house.
