My theory on how they will handle the "aging together"

[TheFirst]

My theory on how they will handle the seamless neighborhood & everyone growing up together.  I've heard many people question, how will it work? How will we all be able to play all our sims at once... with everyone aging and such?

I think they will treat it, like it how it is in THE SIMS 2 - University.  Once you focus on one family in the Sims 3, everyone else continues about their lives and "disappears" into their homes, like they do in university dorms. But they still walk about, age, interact, etc. It's only when you click on a certain house (maybe there will be an option for that) will you be able to see that sim's house and the other family does that rabbit hole thing.

does anyone understand what i'm saying? lol.
