What Townie relationships happen in your game?

I haven't used MCCC. In the way that I play now, I have a sufficient number of families and kids around so I tend to let townies be a mystery if they haven't interacted with any of my various sims. I do periodic aging of the town but with the rotational style, my edited townies get a lot of time before they age out. Most of the really interesting ones get involved in my game in some way.
